"In less than 7 years, Mercedes-Benz plans to ditch petroleum-powered vehicles from its lineup. Focusing on electric, fuel cell, and biofuels, the company is revving up research in alternative fuel sources and efficiency."

If electric cars can be made to charge from ordinary outlets, isn't the infrastructure already there? I suppose the trick would be to get the cars to charge fast enough and/or to last long enough on one charge that you don't have to stop every 4 hours to charge the car for 12 hours at a time, but assuming we can solve that, replacing all those gas pumps at fuel stations with extra outlets shouldn't be that big of a deal.
Basically, I think electric cars are the only real way to handle this stuff long term, but battery technology has to get better. Today's batteries are too heavy and don't last long enough.
I think better public transit is a good step, but I don't think you can put the private vehicle genie back in the bottle at this stage. People are accustomed to private transport, and the more efficient and environmentally friendly we can make that private transport the better.

Most electric outlets have a 15 or 20 amp breaker. That means on the best of days you're only going to be able to get 1.8 to 2.4 kw or about 2.4 to 3.2 horsepower out of it. Unless your car uses less than an average of 3hp while it's running you're going to have to charge it, or at least your spare battery pack, for a pretty long time to get any range out of it.

Okay, well, first let's look at some common outlets in the US. Your standard NEMA 5-15R has a 15A breaker and, while there's a nominal delivery voltage of 120V, you'll probably get 117V or so out of it. That's 1.755kW. Kitchen outlets generally have a 20A breaker, so 2.34kW. The NEMA TT-30R, the standard low-power RV outlet, is also a nominal 120V, so assuming 117V still, that's 3.51kW. Dryer outlets are split-phase, either NEMA 10-30R or 14-30R (the 14-30 ones are properly grounded; the 10-30s are grounded through the neutral). They're able to feed a nominal 240V (we'll say 234V) at 30A. That's 7.02kW The higher power equivalents, the 10-50R and 14-50R, are the standards for range outlets. The 14-50R is also the standard high-power RV socket. This is 11.7kW.
Okay, so these are the outlets found all across the country. The RV ones are especially interesting, since RV parks can often be found in even the most remote places, and I'm sure your average RV park owner would love a new revenue stream, what with RV travel down due to high gas prices. Now, let's take an upcoming EV like the Aptera Typ-1e -- 2+1 seating, 120 miles@55mph, 70 miles@80mph, 90mph top speed, 0-60 in Oahu. They use 60kW PosiCharge fast chargers by Aerovironment. Aerovironment already makes them as big as 250kW.
To get an idea of what sort of driving distances you can get in a given length of time and how those compare to gasoline, there's always this convenient spreadsheet [daughtersoftiresias.org]. Adjust the EV pararmeters to those of the EV of your liking. Explanations of the formulae and parameters are at the bottom.
Oh, and as for Mercedes? Who wants to bet that they'll make one or two EV/PHEVs, one fuel cell vehicle, and do the cheap/lazy thing and simply make all of the rest of their vehicles flex-fuel capable?

Absolutely not. At least in the US, electrical power distribution networks are already are at capacity, and are not even *close* to what they'd need to be:
* Total electrical power consumed in the US - about 12 Exajoules (for more is generated, but most power is lost in generation and distribution).
* Total petroleum power used for transportation in the US - about 28 Exajoules.
The way these numbers are measured, electric cars are significantly more efficient, but still we'd need to distribute *triple* the electrical power distributed in order to stop using gas for transport. That's significantly harder than replacing the tanks and pumps at every gas station.

Don't take my word for it. Take the word of a peer-reviewed study from PNL conducted for the DOE [pnl.gov]. We already have enough electric infrastructure for 84% of our existing vehicle fleet to switch. Of course, not as though it's somehow *harder* to build electric infrastructure than develop new oil fields and pipelines.

I personally believe that electric cars are part of the solution in the long run, but in the short-to-medium term, we've got to work on alternative fuels that can make use of the existing infrastructure (with modifications).

No? How about walking out of your house and to the nearest subway station (for me, 4 minutes), waiting for the next train (3-8 minutes, depending on the time of day) and being taken to your destination, or within a five-minute walk of it. There's no need to buy fuel, no need to have a car serviced, freedom to do what I want while I travel (read, use a phone, sleep, be drunk), much greater safety.
The car is only convenient if the place you live has been shaped around its use.
Its right there, whenever you want it.
So is a good transportation network. Your car isn't available if you've drunk alcohol, or if you're really tired.
Its fast, it can be used by almost anyone, regardless of physical health. No wait times to use it,
Traffic lights, junctions, traffic jams, filling with petrol, servicing, cleaning it.
no sharing it with the smelly unbathed guy, the psycho homeless person, or the screaming infant.
Hardly ever a problem round here.
No stops along the way.
Do you have traffic lights?
And it can be used for trips of any length, to any location, without being forced to walk a mile from a bus stop to the destination.
Unless the place you want to go to is on a road which forbids cars (quite common in Europe in the centre of towns and cities). And in any case, that just means there aren't enough bus routes.
And depending on where you're driving, it can be quite pleasant- driving in the mountains with the top down is *fun*. I've never had a fun bus ride.
Bus rides are usually commutes to work, done out of need rather than for pleasure. Driving in the mountains with the top down is different, that's for pleasure. I've never had a fun commute to work in a car (though I used to like my commute by train, the scenery was nice).
On top of that- cars, to a large portion of the population, are freedom. Freedom to go where you want, when you want. Freedom to live where you want.

A decent transportation system is an excellent substitute. If the buses run all night you can stay as late as you like (and drink as much as you like).

If you live in the inner city, look at:
$100/mo for insurance (+/-)
$100-200/mo for parking (more if you're in Manhattan).
Inner city is a bad example for fuel, but a good guestimate would be $25/mo for a very short commute. Average commute probably ranges from 10-30 miles each way, so 200-600 miles per month @ (very generously) 30 mi/gal == 6-20 gal or roughly $25-$80/mo. Actual figures are probably more like $50-$200.mo.
Car payment (lease) say $300/mo. Car payment (purchased) say $150/mo factoring in life of vehicle. Maintenance say $50/mo over life of car (again, on the low side).
So, realistically, you're looking at $600 per month.
Now look at mass transit. I was paying $320/mo for railpass and subway card. Add in $150/mo for car rental for weekend trips, and it's still better than owning a car. Never mind the fact that parking would have cost me $500 for both sides, plus tolls.
OK, so NY is an extreme. But you are severely underestimating the cost of owning and operating a car.

Can you imagine what kind of electrical infrastructure you would need to transfer the same power over mere wires?

Second, you are ignoring efficiency:
5.8 MWs of energy is far more than it takes to move a car. Gasoline engines are remarkably ineffecient at converting all that energy into actual power.

With no drivetrain loss if you use lightweight electric motors inside each wheel. So you don't need to store as much energy on the vehicle in the first place.
ie: Of the 491.2kW/h energy you fuel up with, you only make use of 122.8kW/h in a gasoline car.
That lower number should be the storage target for an electric vehicle with comparable performance (and cost $17 using your rates). And you get other efficiency boosters almost for free: regenerative braking; freedom to change the shape of the car for efficiency because you don't have to worry about placing the engine above the wheels.
So you're overestimating the magnitude of the problem - and of the design freedoms that come with a switch to electric operation. It is a problem that will be solved within our lifetimes.

As an interesting note, an engine designed with ethanol in mind will actually produce more power than a gasoline vehicle of similar displacement. This is because, while ethanol has a lower energy density per volume of fuel, it has a much higher octane rating and a higher synchromatic reatio (you can burn more fuel for a particular volume of air.) So, you can design an engine to run at a much higher compression for better efficiency (more power from the same amount of fuel,) or you can design a turbo engine to run with more boost (useful in a flex fuel design.)
A great example of this is the Koenigsegg CCXR [wikipedia.org]
There are other issues with Ethanol, however. Some countries with a primarily agricultural economy are converting much of their production to produce bio-fuel. This is exasperating some of the world starvation issues.

Southern California (and the whole state really) is very car centric, which is partly why the traffic around LA is so messed up.
As for trying to get between the major population centers in California (let's say, The Bay Area, LA, San Diego and Sacramento), your only options pretty much are Amtrak and Greyhound, both of which generally cost more then the cost in gas to just drive to whatever your destination is---assuming you have a car which most Californians do. If you start taking into account multiple passengers then the cost difference really becomes noticeable.
There is one potentially bright spot though. If high speed rail actually could somehow materialize into a reality it could offer a compelling alternative to driving or flying, in reasonable time. A major bond measure is on the November ballot to support funding for building the high speed train network in California.
