Autonomous Race Cars

They move along pretty well too, at almost 9 ft/s. More technical information on how they are built is available on a Berkeley page, and there's a video of the winning run for 2002."

Auto Autopilots inevitable

[BeBoxer]

It's my opinion that autopilot for your car is an inevitable development. It will become the only way to keep highways scaling. Adding more lanes to add capacity works to a point, but doesn't work forever. I don't think it's feasable to expect a human to navigate a twenty or thirty lane highway. And the density of traffic which an existing highway can carry is limited by the poor driving ability of humans.

I think eventually high-capacity highways will require the use of an autopilot. Doing so would allow the cars to be run with inter-car gaps which would be suicidal with a human behind the wheel. Most stop-n-go situations are due to bad planning on the part of drivers. They speed up too much when traffic clears ahead, zoom up on the cars in front, and then have to slow down to avoid an accident. This type of driving creates waves of congestion which travel backwards down the highway, and is due entirely to poor coordination among drivers. But there is no reason that under computer control rush hour can't cruise along at 60 miles an hour with a car length or less between cars. I bet you could easily triple the maximum capacity of a highway, not to mention getting everybody to their destination faster and with better fuel economy to boot. The R&D will be expensive, but like any electrics the hardware will be practically free once developed. Compared to the cost of expanding existing freeway's, it will make sense finacially too. I figure it's maybe 10 years out.

American's are not likely to give up their cars for any sort of public transportation, no matter how impractical cars become with rising fuel costs, increasing travel times due to congestion, increasing insurance rates, etc. Most Americans have convinced themselves that they enjoy sitting in stop and go traffic, as long as it's in a car and not a bus. But if we could figure out a way to let them keep their cars, reduce pollution, reduce accidents, let them safely talk on their cell phones, and not have to build mile-wide highways I suspect a lot of us might go for it.
