Will Our Cars Become Our Chauffeurs? 792
Roland Piquepaille writes "According to this long article from EE Times about the 'Self-Navigating Vehicle,' the answer is a resounding yes. Many car experts think that autonomous vehicles which avoid collisions and communicate wirelessly with other cars will be the norm in two to three decades. In the meantime, the enabling technologies for self-navigating cars are emerging, from sensors embedded in the brake or accelerator pedals to more powerful computers. Already, partial solutions exist for adaptive cruise control or for staying in a highway lane. One day, we'll be able to do something else than driving our cars through traffic jams, saving us about two hours per working day. This is the future that engineers are building, but will you accept to be driven by your car? So many people like driving that the concept of a completely autonomous car might be delayed for psychological reasons, not technical ones. This summary contains selected details of the original article."

Would cars know how well they're being taken care of, and what their actual stopping distance is? Would they know to increase the distance from the car in front of them if the roads were wet or icy? If cars did adjust their distance to correspond to their individual stopping distance, would this allow other cars to be set in "agressive mode" (or manual mode) and cut in front of cars with larger stopping distances, forcing them to slow down more?

There is already quite complex integrated software not to mention new navigation software in modern cars, and with the regulation imposed on the automobile industry and the fact that the industry has come to realize that "SAFETY SELLS!" there would likely be a great deal of energy spent on making sure the system is 'perfect' before it goes to market.
I remember my Real-time programming professor at university making mention of a Russian space capsule (possibly Soyuz, but I'm not 100% sure on that) as an example of excellent graceful fail programming. The capsule was in the process of decelerating for reentry when something screwed up. The module was getting erroneous data that was telling it that 'up' was the opposite direction that it thought it was. The program got confused, and firing the rockets would probably drove them straight into the ground. So what happened was that if the data being received was outside the expected bounds, it defaulted to a failure backup plan to return the cosmonauts to earth alive. As a testament to Russian engineering of the day, the programmers knew that inside the capsule the astronauts could survive ballistic reentry. So the program defaulted to its backup of 'fall like a rock'. An example of smart programming because had it attempted to continue despite contradictory data by firing its rockets, it most likely would have killed everyone on board.

Consider the fact that the distances one typically covers in the States are quite a bit greater than almost anywhere in Europe or the UK. Most areas are not that densely populated, and thus do not have many -- or frequently serviced -- transportation options. As a result of this, public transport is not nearly as well-developed or as efficient as the equivalents in other countries. It's not terribly convenient to use public transport to go anywhere unless you can stay within city limits all the time. That happens to be much less feasible in the states than in Europe.
Here're a couple of examples to illustrate my points.
1. I have to commute about 12 miles (~19km) to work every day. Time by bus+subway+bus: 1 hour
Time by car: 20-40 minutes, depending on traffic.
Multiply by 2 (commute back home) -- the difference is between 40 and 80 minutes per day, an hour on average.
2. I have to drive about 220 miles (~350km) to see my parents who live in another city every month.
Time by public transportation:
bus + subway+intercity bus+subway = 10 min + 20 min + 4 hrs + 1 hr = 5.5 hours.
By car, the trip takes 4 hours door-to-door.
Again, multiply by 2 for the way back, and we have about a 3 hour difference. Seeing as I typically go late Friday night or early Sat. morning, and come back on Sunday, 3 additional hours of time that I can spend with my family makes quite a difference. So does not having to be aggravated by crappy buses
I hope this somewhat illustrates my point. And just to make things clear, I'm not talking about some tiny towns in the middle of nowhere--the above trips concern Boston and New York.

PRT can scale better than typical public transit, when you consider both the density of service, and total trip time. Hopefully a more technical-minded crowd can get over the naive idea that big trains can necessarily carry more people. If you just consider a track with one car per second (1 person per car) -- a very conservative density -- vs. a traditional train with five minute headways, the traditional train doesn't look so hot. Especially when you consider the effort in supporting a 40 ton car (that's just one traditional train car) vs. a 1 ton PRT car (and hopefully they could get that weight down considerably as technology improves); the PRT tracks should be way cheaper, and ultimately cheaper than roads. They couldn't actually replace roads, but they could make expansion unnecessary, or even make contraction of roads possible (e.g., removing lanes), and reduce the load on roads so they don't deteriorate as quickly.
PRT is meant to work with urban areas the way they are, not just the way we wish them to be. And the technology itself doesn't require any breakthroughs, even taking into account safety issues.

Making the 45-minute morning commute on the 8-lane, due-east freeway into the city for the 500th time is NOT fun, but I don't really have much of an option if I want to keep doing the job I like that pays my bills. What fun is a "journey" that I've already made 499 times before that involves little more than putting on the cruise control, keeping the steering wheel straight, and hoping I don't get stuck in a traffic jam?
See a difference? That is what an auto-driving car would fix -- I'd be free to use that time to catch up on the news, read a book, browse slashdot wirelessly, do some work, take a nap, shave, actually LOOK at the scenery around me instead of staring 30 feet in front of me, whatever.
I'd ENJOY the journey, instead of dread it!
The goal is to have cars that can drive themselves when you want them to, and turn over the controls when you want them to. I can't imagine car makers would plan for a future where personal transportation vehicles with manual controls will disappear. Despite being 2 miles from a major highway right now, I can drive for 5 minutes and be on any number of dirt roads, which may well never be paved. No one's taking away your steering wheel.

The death was caused when these weights broke loose in the passenger compartment and crushed the hapless man.
Hopefully, it would not continue to carry these weights when there are people in there on production runs, and (presumably) individual people would be easier to move off you if they were to "break free" during the day.
Dude, read your own article.
