      Congrats, You are the first winner of the " I care about something " award. At least you point out that we are all winners if we follow the long term view of helping the planet.

      sometimes it's as simple as walking your kid to school 3 times a week. just a little nudge in the right direction from many people and the planet wins. Small steps towards the benefit of mankind.

      heck, I'm learning to Rollerblade, this way I can skate to work 2 times a week. it's an idea that I might end up liking a lot.

        When I was living in Southern California I rode my bike to work about twice a week. It was normally a 8 mile drive, however there was too much traffic along the road. Instead, I rode three miles extra to ride on the wonderful bike path that stretches from Redondo Beach to Santa Monica/Malibu. Riding along the beach was a wonderful way to start and end my workday!

        Now that I'm living elsewhere and have a longer drive to work, I've looked into alternatives to save fuel. There's no carpool/vanpool from my house to work and public transportation is out of the question (It's possible, but involves a 3 mile drive to train station, three trains, and 2 hours).

        For now I'm stuck with my Honda Accord however at 33MPG I can't complain, even if gas was $3 a gallon again. I noticed that when gas prices were over $3 a gallon, most of the people complaining were drivers of SUVs and pickup trucks. I personally don't have a problem with gas being $3 or even $4 a gallon. The cheaper the better, but the net effect of higher gas prices would be lower consumption. I still miss the days when $10 would get me over 300 miles with my 89 Honda Civic!

      Many thanks for pointing out that when the environment wins, so does everyone else.

      While it might not be the cheapest technology out there, even the article that allegedly "debunk" the cost effectiveness of hybrid technology goes a long way to show that environmental options are not the money-draining nightmare they have been presented to be.

      the only real winner after a hybrid purchase is the environment.

      Oddly, this particular analysis is only looking the economic factor, which anybody who's ever priced out a hyrbrid knows that owning a gasoline car is still cheaper.

      It would be interesting to see a similar paper on Total Environmental Impact.

      Gas-only cars burn more gasoline, which means not only more pollution from the car's exhaust, but also more demand for oil refineries.

      A hybrid car requires less gas, but it also has a massive battery which will need to be disposed of safely in a few years. What would it be like to manage the disposal of these batteries if there was suddenly tens of millions of such cars driving around?

      I'm sure things would still favor the hybrid by a pretty good margin, in spite of issues like this, but it would be interesting to see a complete comparison. (One that is not from somebody trying to sell us on the idea of owning a hybrid.)

        I notice an often missed point in many hybrid articles. Hybrids derive thier electric power from regenrtve braking and only make use of thier electric motors when crusing and driving around town. If you have a 40 min highway commute the 4cyl gas engine is going to be doing most of the work and you wont even see the improved gas mileage of a hybrid.

        Its emissions will be the same as any other 4cyl car as well.

        The mentioned incentives to allow hybrid cars to use the HOV lanes actually hurts since they see thier best fuel econ in stop and go traffic.

        For real high economy, low enviromental impact look toward diesels for the time being. New diesels produce much lower emissions (sometimes better than thier unleaded counterparts) get excellent gas mileage (north of 40mpg for many models). Further by desgin diesel engines are multi-fuel so when the next replacement for dino fuel comes around, most likely your diesel engine can run it with little or no modifcation.

        Yes a diesel engine costs more, it will also last longer and be more reliable than gas engines. Not to mention for the real geek you can make your own fuel for pennies a gallon.

            Not true. The current diesel fuel standards in the US prevent the cleaner diesel engines from being sold. The engines exist and are being sold everyday in Europe. It's our dirty diesel fuel that is holding them back. Thankfully our diesel standards are set to go up in the next year or two which will open our markets to these very efficient and clean diesels.

            No production diesel can currently meet California emission standards in the US. Mileage per gallon cannot be compared between diesel and gas as a measure of effiency because diesel has over 30% more energy per gallon than gasoline.

            And that somehow nullifies the comparison? Why?

            And, your data is completely wrong. Diesel contains 139,000 BTU/gallon. Gasoline contains 124,000 BTU/gallon. (both figures rounded to nearest 1000) That's about 10%, not 30%.

            However, the diesel combustion cycle is MUCH more efficient than most gasoline (Otto) combustion cycles. The Atkinson and Miller cycles can increase gasoline combustion efficiencies, but usually in a narrower operating region. THAT's where the difference comes in.

            NOx emissions are particularly problematic with diesel engines. The higher compression ratios create considerably more work for the catalytic converter.

            And continuing studies show that NOx emissions are not the "root cause" of air pollution that scientists once thought they were. "Cats" on diesel engines are near worthless, and NOx is almost completely handled by combustion technology. Run a modern diesel on 100% biodiesel, and even the emissions argument goes out the window. Your "net" CO2 emissions are drastically reduced (they would go to ZERO if the biodiesel production uses methanol derived from an organic source instead of natural gas.) Someone also addressed the cost "premium" of buying a diesel vehicle. The cost for the diesel upgrade on the new Passat is $255 (you read that right, two-hundred fifty-five 'murican dollars), and the reward is roughly 35% better fuel economy, and the ability to run on a renewable, sustainable fuel. How much over MSRP are people paying for Prii again?

        Current hybrids use Ni-MH batteries, which aren't particularly toxic from a disposal perspective, and, more importantly, conatin valuable metals that can be recovered through recycling.

        Toyota, for example, pays a $200 "bounty" for dead batteries, because the nickel in them is quite valuable.

        Ni-MH is probably the most "eco-friendly" battery technology. It's certainly worlds better than Ni-Cd.

          Lead acid batteries, which I think are what are used in most hybrids, are the most recycled commodity in the country.

          I think that hybrids generally use NiMH, not lead-acid batteries. For instance, the Toyota Prius [wikipedia.org]. But I think that NiMH batteries are just as recyclable.

            And this is a key point that the author overlooked in the economic analysis. It's similar to saying the world's space programs have all been a total economic waste and reaching that conclusion by eliminating all of the economic side effects that have resulted from the technology that went into those space programs. That's a political statement, not an analysis.
                    The large-scale production of NiMh battery arrays that go into hybrids is rapidly reducing the unit price of these high energy density storage devices. Now, is it really a great lap of logic to think that low-cost high energy density rechargeable electricity packs might find use in other products besides hybrid vehicles once the price is right?
                    Not only has the price of large arrays of NiMh cells gone down dramatically in a short time, but the early stages of an upramp in large arrays of Li-Ion batteries is beginning as well.
                    But wait, there's more!
                    Supercapacitors. Did you know that the regenerative braking system in Japanese hybrids uses arrays of supercapacitors? Again, the technology has been around for a long time, the real issue is price and the price doesn't come down until we get economies of scale and we don't get economies of scale until we get a consumer grade product that uses masses of these devices.
                    The availability of these high energy density devices at low prices is almost guaranteed to have fall-over effects in all sorts of different consumer markets. Unless you take those significant advantages into consideration, it's really just a snipe to draw a conclusion about the lack of economic value in a hybrid car.

                "The author was probably aware of these issues, but he didn't include them because don't factor into the consumer decision."

                Really? If that were the case, almost zero hybrids would have been sold. The math in this article is not rocket-science, he is stating the obvious, and I imagine 98+% of the people buying them are full aware of the simple economics. I think your point may be valid for many, but certainly not all. Many, many people have bought hybrids (or are considering one), paying a definite premium, solely because they believe they are doing the right thing for the environment and the next generations of earth inhabitants.

                It definitely does factor into many (not all) consumer's decisions.

          What is with this argument? Exactly why is it bad to focus on greener technology while still providing people with transportation, energy, food, etc? It seems like some economists shun green like it's guarenteed to single handedly collapse the current market, while some environmentalists see the market economy as the single driver of the destruction of the planet.

          As is with just about EVERYTHING in life, moderation is always better than extremism. Large companies that drive market forces should still strive to pollute as little as possible, and anyone that things that the world is fine and not in need of a little love from newer technology is crazy. Anyone that thinks we shouldn't strive to develop newer and better technologies that do in turn pollute less is truely delusional.

            Why should we have to pay more for our phone service/electricity/roads/etc, etc, etc just so you can afford yours? If you like living in the middle of nowhere so much then be prepared to pay for it.

            Three reasons.

            First, much or most of the non-office style work is done outside of cities. Most city dwellers don't want to work at a meat packing plant or live next to one. Most city dwellers don't want to work at a waste water treamenet plant, or live next to one. Most city dwellers do not want to live next to trash incinerator, oil refinery, pumping station, truck depot, concerete plant, or pig farm. Yet just about all city dwellers want sewer service, water, eletricty, delivery trucks, and all the stuff that can't be cheaply or "not in my back yard" done in the urban centers. I've lived next to a 4000 acre chicken farm before. I have a feeling that all the egg and chicken eating residents of NYC would be less than willing to give up central park to raise chickens on. So that's the first reason. Unless you want these things in the city, you have to be prepared to support less-than-urban areas.

            Reason #2, is that these "red staters" grow the grain, raise the cattle, and do the argicultural work without which the country cannot literally survive. Look at where the food that we both consume and export is grown: the breadbasket. Again, this is not possible to achieve in an urban center. Urban centers are net importers of items like food and energy.

            Reason #3 is that development trends are such that you can't really create new urban centers, and so, people are stuck living in the "middle of nowhere". New communities that do pop up are generally suburban; we aren't seeing a lot of new cities being built. If the rural population tried to move into the urban centers what you'd see is an even tight real estate market and yet another escalation of housing rates. This would just lead to even more sprawl.

            Finally, I think you are overestimating the effect of the rural and surban subsidy, and understating the unreimbursed services provided by the rural population. The founding fathers recognized from day one this divide between the urban and rural citizen and this led directly to the split system of representation - the two per State senate and the population based House.

        Wikipedia's article on battery operated vehicles is pretty damn interesting. Why was that technology abandoned? There's no reason why with modern technology we couldn't build an all-electric car that had comparable performance to any hybrid (they already did in every category save range) and similar range (the missing piece). Who here wouldn't own a battery powered electric vehicle if it had about 300-350 miles of range?
        I suspect time and availability of recharging are factors.

        When the gas tank gets low, it's a few minutes at the station to refuel. With batteries you're looking at a few hours to recharge. Also, where can you plug in to recharge? In an apartment without reserved parking, you can't guarantee being able to get to a plug. I can imagine most landlords having a problem with long extension cords running across the parking lot.

        If a gasoline-powered car runs out of gas, the driver can hitch a ride to a station and back with a couple of gallons. What do you do when if/when your batteries run out? Getting towed is expensive.

        The early electric cars were also just plain ugly [ieee-virtual-museum.org].

        Look at how much toxic chemicals is in a battery. Now factor in that you have to replace the batt every 2-4 years. Not only does it end up costing you more, but you're not doing much besides thinking you're helping.

However, since this local government doesn't have to pay taxes on the gasoline it purchases, it can get it for very cheap. He also found that it would take well beyond the life of the vehicle to become profitable.

    I think it's kind of unfortunate, really, why hybrids cost so much more than conventional vehicles. The tax incentives in this case were of no use, as I said, because this agency didn't pay taxes.

          This article [jewishworldreview.com] points out that you're comparing apples to oranges too:

          But profits can't be judged by dollar amounts alone. What counts is the percentage of revenues those profits represent. "Our numbers are huge because the scale of our industry is huge," Exxon CEO Lee Raymond tried, probably in vain, to explain during last week's big Senate hearing on oil company profits. Exxon's profits last quarter amounted to 9.8 cents for every dollar of sales. Is that obscene? Well, it was more profitable than Shell (which netted 7.8 cents of each dollar of revenue) or Chevron (6.6 cents) or BP (4.6 cents). But compared to Coca-Cola (21.2 cents), Bank of America (28.3 cents), or Microsoft (33.2 cents), it was nothing to write home about.

          Oil companies invest billions. getting a billion (or even 100 billion) isn't that much. The government, on the other hand has "made" $2.2 trillion on gas taxes. Thats money you and I could have spent elsewhere.

          The government doesn't have enough to maintain roads? That's because the so called transportation money goes elsewhere - even money spent on transportation is more likely to go to new projects as that gets better visibility. Repairing roads isn't sexy and it doesn't get you votes.

    Anyone who purchases a hybrid without doing at least a really basic cost analysis is an idiot.

    We purchased a Prius back in June. We knew that unless gas stays at like $3 or $4 a gallon, it wouldn't really pay off (and then Katrina hits, and we actually paid $3 a gallon for a few weeks).

    It's not a cheap car, but fully loaded, it really wasn't that big a difference for us compared to, say, and Accord. And it gets better mileage. You can run the A/C in stop-and-go traffic with virtually no gas consumption (the gas engine cycles on for 30 seconds every five minutes or so).

    Plus, it's incredibly geeky. What's not to love? We've even been able to fit a lot of stuff in it for weekend trips (suitcase, assorted other bags, cameras, etc., plus a stroller, pack-and-play, and, of course, the baby), even leaving the back seat pretty much free of extra boxes or bags. You'd never think there was so much space to look at it from the outside.

    Bottom line: Don't buy it to save money. Buy it for the clean air impact, and especially to support the longer-term development of hybrid technology. Imagine if this were in *every* Toyota car -- their CAFE numbers would probably be up in the 30s or 40s (it's probably in the 20s right now).

    Nice analysis, but like most of these type of analyses, they ignore some important factors:

    Environmental cost of manufacturing NiMH batteries
    $ Cost of replacing batteries at end of useful life (which is likely before the vehicle's useful life is over)
    Environmental cost of disposal of NiMH batteries (likely 2 sets per vehicle during useful life, 100 pounds+ each set) That's a lot of heavy metals to dispose of.

    This math does not take into account the ass factor. There are a lot of chicks that are hip to this save the rain forest crap and they may be more inclined to open up for a guy who "cares" about the ice melting. Think of these tofu-eating broads as an untapped market and get yourself some rubbers and a set of 21 inch rims on your Prius and you're ready to go. You might not even have to use rubbers with these girls if you play the latex is bad for the pandas card.

    Actually, the analysis is based on MSRP, but I doubt anyone pays MSRP anymore. In fact, I've two Honda civics, one standard (for my wife), and one hybrid. The hybrid came with more options standard and ultimately I argued the price down to about $1400 of the normal Civic. I've made that up between tax breaks and gas savings, but better still it's ULEV that can go 600 miles on a tank of gas. That's pretty good.

    As far as maintenance costs -- both have been excellent.

    The article seems to be assuming that Gas prices remain constant through the life of a car. Anyone believe that? How about the same calculations assuming a 10% per year increase in gas prices (which they were this year before Katrina).

    from the article:
    Gas-electric hybrids are the most fuel-efficient passenger cars on the road and ecologically there isn't a more viable option. Until something big changes, though, the industry-high efficiency can't economically offset the steep sticker price.

    This is quite a sweeping claim, and one that I would contest. The VW Jetta TDI (diesel) gets consistently 55-60 mpg -- about as good as the best hybrids out there. What's more, diesel fuel uses less fuel in its manufacture than regular gasoline, meaning that the "embedded fuel" is significantly lower.
    I tend to agree that much of the hybrid talk is hype and that getting 25 more miles out of a gallon of fuel does not make your car "green". What's much more, though, is the idea that hybrids get better mileage than any other cars on the road. Diesels, particularly some of the models by VW and Audi (in Europe, at least), prove that efficiency is more than just fancy technology.

      I'll second that.

      Not only do VW TDIs get phenomenal fuel mileage, they also make power. Something hybrids do not do. Granted, I modded my TDI, but it's making 300 ft lbs of torque and still getting 45 MPG. If VW actually built an anemic TDI (that is, one that only made as much power as your average hybrid) I would bet it would double the fuel economy.

      Diesel motors are more efficient by design. They have lower exhaust temps (less energy wasted through heat) and they don't have a throttle (when your foot is off of the throttle on a gas car, you've turned the motor into a vacuum pump - again, wasting energy).

      That being said, why hasn't anyone built a diesel-electric hybrid car? Surely it would maximize power & economy?

    I'm guessing the reason the article's author chose to structure things in terms of a bunch of new cars (hybrid and not) vs. a 1999 Honda Accord is because the author owns a 1999 Honda Accord. This alone gave the article an unnecessary slant. The basic conclusion -- that hybrids are more expensive to own on an installment plan than comparable standard and diesel cars -- is valid, but the gratuitous comparison to a six-year-old car exaggerates the differences by making everything a bad proposition compared to his 1999 Accord.

    Heck, how do I get a 1999 Accord for $4000 anyway? By lucking out at an auction? By buying one off my favorite aunt? Last I checked in my area, 1999 Accords in decent condition fetched at least 50% more than that even through private sellers. Use of honest numbers for comparison woud help. That and factoring in repair costs. I doubt his 1999 Accord is still under warranty, making average repair costs more expensive.

    Also, his favorite new-car-to-new-car comparison was between the Prius and the Toyota Corolla. The Corolla, though bigger for 2006 than past models, is a compact and the Prius is generally regarded as mid-sized, Edmunds database notwithstanding. And comparing a Prius to the stripped-down base Corolla is also a bit dishonest. The base Prius is equipped comparably to one of the upgraded Corollas that sell for $15,000-$16,000, not to ths stripped $12,000 model. Want a decently-equipped Toyota for $12,000? Go look at the Echo or whatever they renamed it. That's even smaller.

    The TCO advantage still belongs to the quality non-hybrid gasoline and diesel vehicles, but not as much as indicated here. And as gasoline prices pick up again this spring and likely top $3/gallon for good, the smaller-than-stated gap will narrow considerably.

    I've had a 2004 Prius since November 2003. I'm very pleased with my car, and I'll keep it for many years to come, I think. One thing that keeps coming up is that I didn't save any money. What I don't understand is why that focus is applied to the hybrid and not other cars? You can pretty much get a fully functional, well engineered car today for around $12K. So every dollar you spend over that is just for personal taste. When someone buys a $60K BMW, I don't hear people saying "You know, you didn't save any money".

    I guess the idea that you might save money with a hybrid casts the image that most people who buy them are out to save money. I'm not. At $24K, the Prius is only a bit more expensive than other cars of it's quality -- but like a BMW purchaser, I would have bought it for even more. BecasuseI think it's cool. I like the idea of using as little oil as I can while still living a convenient and comfortable life. I like the idea of polluting as less. And most of all, I like the idea of voting (with my dollars) for changing technology in automobiles.

    So, just want to point out that not everyone who buys a Prius is doing it for a financial reason -- probably not more than with any other car.

    Cheers.

    Ahhh, did anyone check the math. It looks a bit off. First he uses a 1.15 multiplier to account for 'other costs' THEN adds it to the loan value (i.e., interest oriented). If you read the endnote that is based on the fact that loans are for 115% of the value (payoff on old car?). How is that a legit 'cost' of the new hybrid car?

    Second he is using the full cost of the hybrid. He is assuming that you dump a perfectly good car and buy a hybrid, NOT that you are bright enough to buy a hybrid when it is time to buy something. That is, he is assuming it is the full cost, not the incremental cost of the hybrid. While that MAY be a correct financial analysis, it is unlikely to be a real world analysis (IMO).

    If I want a $22K hybrid and my other choice is a $18K car/SUV at 25MPG, then the 'additional capital expense' is $4K NOT $22K. $4K * 1.15 (assuming I use his magic math) is $4.6K incremental cost at 5.25% over 60 months that's about $88/mo in payment. Given the gas savings and higher trade in allowance, the case for a hybrid may be closer than he paints. Of course that assumes the competition for your car dollar is an SUV at 25 MPG if it is a small car at $15K and 30MPG then the hybrid case is less good.

    The real issue is during a "I'm going to buy a new car, what will it be" purchase period. It is fair to deal with incremental costs and incremental improvements in gas mileage/trade-in value. As I read it, the article assumes a 'forced trade' at full cost, not incremental costs. I'm not sure that is a fair comparison.

      The U.S. doesn't "underprice" fuel; Europe taxes and regulates the bejeezus out of theirs.

          However, the arguement is that Europe "taxes the bejesus" out of their gasoline in order to encourage mass transit and energy saving vehicles.

          In the U.S., while in principle this would be a good idea, there just isn't the urbanization that there is in Europe. European cities aren't built for car commuting - hell most of them had to be upgraded for horses 1400 years ago. Narrow, winding streets, and cobblestones, do not encourage cars. In the U.S., everything is younger, and most of it is built to accomidate cars, with wider streets, etc. As a result, the U.S. has always had that huge suburban and rural population that drives into work. In many places, there just isn't a mass transit option. I lived in metropolitan Memphis for a long time; there's no mass transit to speak of there, other than an aweful bus system. It's too close to the mississippi and too close to the water table for a subway (no one has a basement in Memphis). But, you know what they do have? A "beltway" (I-240) and a LOT of parking.

          It's only feasable to use mass transit for everything if you live in one of the cities like Washington, DC, which has an excellent metro system and inbound rail system, or New York, who's subway system, while not pretty, can get you anywhere you need to go.

          Driving places is a culture in America. Very few of us live close enough to walk, or even bike, to work. A friend of mine told me about an exchange student from Estonia whom he befriended, and how when they went to D.C. one day, and Dimitri saw the "Springfield Interchange" (the Mixing Bowl), it flipped him out. A road that's seven lanes wide in each direction, with flyover ramps going everywhere, people merging at 60 miles an hour 10 feet apart... it was like nothing he'd ever seen before.

          Raising taxes on gas to $6-$8/gal in the U.S. would crush the economy. We're just not built for it. We're slowly emphasizing mass transit and there's been a small movement towards local community envolvement (i.e. not driving 50 miles to work, but working where you live), and we'll get there... but let's not get drastic.

            As for needing wars to get that oil, these wars come about by interacting with a stunted, xenophobic society. It is unfortunate that this happens.

            This is the kind of rationalization about wars that scares the hell out of me.

            If you have to go to war repeatedlly to maintain your energy policy, despite having being bitten once 30 years ago, then something must be wrong with your policy. Especially when alternatives to oil already exists.

            It's just that the populations of Islamic societies don't want to be in contact with Westerners.

            This blanket generalization scares me even more.

            But just to say oil is evil, etc. is not a solution.

            Nobody is saying oil is evil. It is the irresponsible use of a limited resource, in an enviromentally damaging way, maintained by a myopic national energy policy which uses wars as a policy tool, that is evil.

      I think I disagree with your premise that the US energy model is 'fundamentally flawed'. Surely, it makes sense that cheap energy will stimulate economic growth and add to the wealth of the nation. To this end, it is justifiable to have affordable gas. Venezuela is using this idea right now, last time I checked they were retailing gas for 4 cents/L.

      With respect to this line of reasoning, the big white elephant in the room is the environmental costs. What is the point of enriching a nation if it become toxic in 50 years? What need to be happen is for the global economy, not just the US, to come to some concensus on the future of energy availability. More and more signs point to peak oil occuring now or in the next 5 years. That means from now on (or not far from now) energy will be a premium commodity and the costs associated will inflate. Inventing efficient gasoline cars is a useful tactic to stem the tide of oil scarcity, but oil is still dirty. Technology like fuel cells and hydrogen power must be the focus. Preserving the oil economy is folly.

      Many people realise this and have argued that the global oil economy is a disastrous thing. I, for one, have no confidence that it will change, however. We are addicted to oil. Everyone in the developed world is addicted to oil. We are not going to stop. It is like an alcoholic who drinks himself to death. He knows he is killing himself but he keeps drinking. That is us. We will use oil until the world is toxic or the economy collapses plunging us into chaos. I'll be dead by the time it happens but unless there a radical shifts in the next ten years I think we are doomed.

      So, to single out the US oil stategy is unfair. We all suck.

      Have a nice day.

      Just a couple of simple points:
      1. I currently pay $2/gal and $1 of that is tax
      2. The US is over twice the size of Europe so that does present some barriers to public transportation.
      3. Actually, I agree with you in principle, just wanted to make the above points.

      The batteries in the Prius are not lead-acid, as another poster pointed out. They're NiMH. In addition to that, they are warranted for 8yrs/100k miles, and expected to last the lifetime of the car without replacement, so it's unlikely that there will be much more than one battery pack per car lifetime on an average basis.

      Toyota recycles them completely, chemicals, metals, case, wiring, etc... and pays a $200 bounty to encourage people to do so. Their recycling program has been in place since the Rav4 EV, so it's a fairly mature process by now.

      brejc8: Fortunately in Europe we also have a system of public transport which most environment minded people (like myself) prefer to use rather than pretend we are doing our bit through the purchase of a new car.

      No, unfortunately in Europe our population distribution is massively unbalanced, squeezed into tiny mega-cities constrained by historical boundaries, that have great public transport, and everyone who lives in a rural area gets f**ked over.

      My local bus timetable [carlberry.co.uk] (local being two miles away). Yup, that's right; Tuesday-Friday we get 1 bus a day; you can go, but you can't come back until tomorrow. On Mondays we get two busses; sadly they go to different places so you still can't get home. No busses at all on Saturdays or Sundays. None of these busses go within 5 miles of where I work. None allow bikes on board.

      Given the total lack of understanding of rural communities by European townies and so-called "environmentalists" (who, ironically, usually have about as much knowledge of the countryside as I have of the Docklands Light Railway), quite frankly I'm just waiting for the day when they draw up the cattle trucks to forceably relocate all country folk to London. No doubt the townies would still complain about the cost of housing even then (CLUE: stop all trying to live in one small space, duh).

        You do realize that the situation in Europe would be identical to that of the US if gasoline/petrol was priced similarly, right? I know several Europeans who came to the US with this attitude only to eventually find themselves purchasing a gas-guzzling SUV.

        Not much to do with oil prices; more to do with infrastructure. I can't imagine getting by in the US without a car, unless I was based entirely in one of the larger cities, say New York. Otherwise, how are you to get to the mall to buy food and clothing?

      The only reason to buy a hybrid is show other people how much you care about the environment: it's a statement, not an answer.

      Okay, mr-stereotypical-SUV-driving-cellphone-talking mcdonalds-sucking-American-corporatist-pigdog, some of us actually do care about the environment.

      Very few people can tell that I use all CF lighting in my home and pick my CPUs based on power consumption (Athlon 64 all the way, baby!). My lawn "only" looks healthy, not the bright-chemo-green I could get by dumping fertilizer and weed killer on it. No one but me can tell that I go out of my way and pay more to fill my (SO's) car with B20 biodiesel. That I use biodegradable laundry detergent and non-chlorine bleach. That I manually duplex all my printouts, thus using only half the paper (and for personal use, I'll even do 2- or 4-up per side as well). That I post on Slashdot using 100% recycled electrons.

      You can't tell any of those things from a casual observation (well, I suppose if you came into my house you might notice the color of the CFs rather than incandescents). Therefore, I can't possibly have a "oh, look at me saving the environment! Look, look, I care!" motive. Nor can you attribute it (like the FP) to purely financial goals - Some of those save me money, some cost me more. The net gain goes straight to helping YOU breathe better.


      Unfortunately, I suspect that more often than not, you have it right. But hell, I'll take even the slight improvement of faux-environmentalists over a proud SUV owner any day.
