this_boat_is_real writes "Rather than project info onto a portion of the windshield, GM's latest experiment uses the entire windshield as a display. Small ultraviolet lasers project data gleaned from sensors and cameras onto the glass. General Motors geeks are working alongside researchers from several universities to develop a system that integrates night vision, navigation and on-board cameras to improve our ability to see — and avoid — problems, particularly in adverse conditions like fog."

        Since it overlays the entire windshield, you wouldn't have to take your eyes off the road. If they had a small LCD that had video of the road with this superimposed over it, you would have to stop looking at the road and look at the screen, which would be dangerous for obvious reasons (not the least of which would be lag time..."objects in screen are closer than they appear", and all that.)

        Then again, it would make windshield repairs quite costly...

    • Actually GM already has this available in a HUD system on High End Models. They've combined Low-Light Camera's with IR Features that activate with the headlights. It's purpose is to provide a clearer veiw of what's in front of you during the night. Guess what, it works quite well and is one hell of a safety feature that I want on all cars.

    I live west of my place of employment, and the recent time change has given me it's yearly double-whammy. When you live west of where you work, it means that you're driving east in the morning to get there, and west in the evening to get home. Depending on start and stop times, it means that the sun can be right on the horizon, blinding you at both times. This happens for a few weeks each spring and fall, until the sun rises earlier and sets later, so that the visor can adequately and easily block it. Then time change comes, knocking the sun back down to the horizon.

    I want an "active windshield" that knows where my eyeballs are, knows where the sun is, and blackens just the right spot (with a little margin, of course) to shade my eyes. Compared to that, any heads-up displays are secondary.

  • Its most importantly the roads and drivers.. Drivers being one of the hardest things to fix but roads being the expensive thing to fix. Some roads are great, but some are destined to claim the lives of hundreds of people over the life span of the road.

    What i don't get, is why we don't engineer our roads to be safer? If you build a road between a valley and there are 100 deer accidents a year, don't you think it would have been better to have built a raised road so the deer can go under the road and thro

They also costs $150+ each; $30 tires that float around when it rains are more appealing to consumers, because what do I need fancy tires for?
    • ..Roads are cheap in contrast to lives

      But the people who maintain the road do not pay anything when you die ... so roads look expensive to them

    • If you build a road between a valley and there are 100 deer accidents a year, don't you think it would have been better to have built a raised road so the deer can go under the road and through the only choke point in the entire valley rather then get themselves killed and a few humans while they're at it?

      It's a lot cheaper and easier to just shoot all the deer and build a normal road.

  • Unless this is done VERY carefully, I'm afraid it'll just end up distracting most drivers. Yes, head-up displays have existed in fighter jets, etc. for decades, but those pilots are highly trained to process all the data given to them. Throw an average driver into a car that suddenly starts highlighting road signs, etc. and you risk distracting him. What happens if the system freaks out as you drive down a street with tons of road signs? You could end up flooding the windshield with lots of neon lines a

      That doesn't sound very hard. You can figure out where the driver's eyes are by the orientation of the rare view and side view mirrors. On that note, since you're supposed to adjust those mirrors before you start driving, it's just one more thing to adjust before you drive off.

    It can improve safety of driving in poor weather conditions immensely comparing to current situation. But I'm afraid it will have a reverse effect in reality: increasing driver's confidence ("the HUD displays the road far ahead, so there is no danger") will result in increasing the speed in these conditions, and result in more serious accidents because the system can't foresee everything - obstacles on the road, slippery surface, other cars that don't have it and drive blindly - the kind of accidents slow and cautious driving would help against, or at least minimize impact.

      That's what scares me, too. It's like 4WD here in Maine - if you go down the highway after a snowstorm, you'll pretty much see only two types of cars - very small light cars and SUVs. The former because the cars simply can't handle the conditions, and the latter because some 4X4 drivers became severely overconfident in the capabilities of their vehicle and think 4X4 is some form of magic glue that sticks the wheels to the road. The 4x4s are the ones that get really banged up, because their drivers have been running at or above the speed limit.

      That and the possibility of some sort of malfunction at an ill-timed moment. A bunch of drivers tootling down the highway in deep fog, all tailgating one another just like they do in clear conditions, and the second car in line has his sensors hit by a rock kicked up by the first car, and it knocks the sensors off kilter or out of order. Second driver is now completely blind in heavy traffic.

      If used to enhance defensive driving, this kind of system could be really useful. Especially using senses like IR to detect problems that may not be very visible (pedestrian in dark clothing walking up to crosswalk at night) or providing useful safety information (paint the 3-foot barrier line around the cyclist, and estimate whether you have enough room to safely pass him based on the speed of oncoming traffic in the opposing lane). Combine this with GPS to "mark" the road you want to drive down, and maybe even "paint" the road names on roads you are passing by, and turn-by-turn GPS is suddenly a lot less distracting.

      But that's not how it's going to be used, at least not exclusively. For every driver using this as additional information while driving at a speed they can support without the enhancements, you'll have at least one that turn the system on, put the "Top Gun" soundtrack in, crank it to 11, and drive down the highway in 20-foot-visibility fog at 70MPH following the painted lines.

      • I'm from Buffalo and went to school in Rochester (Western New York), and one of my greatest pleasures during those years was driving home and back after or during a big snowstorm. I had a ten-year-old FWD Saturn - really not a great car to drive on snow and ice - but I learned to drive in cheap cars in snow and ice so I know how to handle it. I would often drive somewhere when it was really bad specifically because I knew I could, I didn't really care if the car got damaged, and I knew there wouldn't be any

          Why the thruway is designed with ditches on both sides I'm not really sure, when I know the designers understood about snow and ice making people run off the road, but it sure makes a great trap for cars.

          You've just answered your own question. I'm assuming by "ditches" you mean relatively gentle embankments, and not severe dropoffs.

          If a car loses control at 65MPH on ice, it's a spinning hunk of metal ready to take out anything in its path, and that path will rarely line up with the direction of the road.

          If you put a guardrail the side of the road, that vehicle will bounce back into traffic. You only want guardrails in places where it is MORE dangerous to go off the road (severe dropoff, going over a bridg
