    After being at a school with several thousand foreign students, I'm inclined to believe that some of them can *never* be taught to drive.

    It's not that they're foreign; it's that they've rarely been in a car before arriving in the U.S. Here (and in other developed countries) we've been in cars from birth, and flowing through traffic. That very flow is missing from these folks; it's entirely an artificial environment. There's some amount of instinct we pick up along the way. Maybe it's like language; far more easily and naturally learned while young.

    As a group, those learning to drive here aren't merely worse than more experienced drivers. As a group, they seem to be worse than new drivers (as a group).

Making it safe to, say, read a book while you're cruising along.

      Or possibly, a rear-facing distance sensor could detect how far back is the car behind you, and if the space is wide enough, the system could then safely slam on the brakes. (Passengers had better be using their seat belts!)

      Traffic jams, slowdowns, etc. would need no special logic to handle. As long as the car is aware of where the next one in front of it is, all it needs to do is drive at the highest speed that keeps it a safe distance away, without exceeding the limit.

A momentary snap of the wheel, at highway speeds, can indeed cause an accident. Releasing the wheel gradually should take care of that.

This is one solution. Another solution would be to bury the dots flush with the road surface, though this might be expensive.

Then comes avoiding the small stuff (kids, balls, cats - well, maybe not cats - just kidding)...

    I think we shouldn't be concentrating on a complete computer guided car concept, but more on an advanced cruise control for vehicles. Front and rear looking radar (maybe side radar too), combined with a simple vision system (a single B/W low-res cam should do OK here), and smart dots - these things could be done in such a way to make an easy an affordable "smart" cruise control for the freeway commute or interstate drive.

    The radar portion would be for speed and avoidance control - this portion is already in limited use in luxury vehicles, as well as some commercial vehicles. The cam system would be forward looking, and would be a system to do edge detection - to help keep the car centered going down a lane. The processing power to do the real-time edge detection and centering should be able to be accomplished with current cpu's, at max maybe a small Beowulf style cluster parallel computer (to process in sections of the image - kinda like the 8x8 processing of jpegs). The final portion would be the smart dots...

    What I am calling a smart dot here would be the only infrastructure change needed - and if such a thing hasn't already been created and patented, well, it probably should've been. If not, then what follows I am placing under the GPL - the design, and implementation of anything remotely like it (I doubt this will hold up in court, though). Anyhow...

    A smart dot would replace those dots that separate the lanes on the freeway. The new dots would be similar, except that they would have a small circuit in them that put out a very low power 900 Mhz signal, that can only be detected by being near to the dot. The lower edge of the dot would be 3M reflective white, the upper top curved portion would remain clear, to focus sunlight onto a small solar cell to recharge a small NiMH batttery that powers the thing. This "lens" would only be about the size of a quarter or so, maybe even a dime size hole would do it. At any rate, the rest of the dot would be the 3M white, so at night (the battery should be able to last through a night of use - this thing will be very low power) it will show up in the headlamps of the car as normal. This same style dot could be used for the frustum/rectangular style dots, with only a few simple mods.

    All the dots emit the low power signal, so low you must be within a foot or less to pick the signal up. Sensors on either side of the car would pick the signal up, so that the car knows it is drifting, and can compensate left or right, and update what it is seeing in the camera vision system to account for the drift. These dots would be the last line of defense (well, not the last line - since this IS a cruise control, the driver is still behind the wheel, and can take over in an emergency). The dots could also emit information, such as a certain exit coming up, or cars need to slow down for road work ahead, or merge left/right (they could be programmable as well - maybe these things use a funky iPic, like that webserver). If they really wanted to be cheap, the dots could encase small rare-earth magnets, and hall effect sensors would be placed on the cars (with appropriate compensation for the earth's magnetic field). However, these kind of dots wouldn't be as flexible, though they would cost only fractions of a penny more than the current dots in use, and probably wouldn't take much to retool for manufacturing them, vs the smart dots.

    This kind of system, while not as whiz-bang, would solve a LOT of problems (such as people not being able to merge properly, and vehicle density issues vs speed). It might make traffic move smoother during rush hour, and make it easier to get on and off freeways during these times.

    It won't allow you to read a paper or take a nap and catch those few extra minutes of sleep while you go to work - but when it comes to cars, I wouldn't trust any system to allow me to do that!

  42. The real problems are legal. by ucblockhead · · Score: 4
    The real problem with getting automated drivers on the road is legal, not technical. The way the legal system works (at least in the US), any company that sells these is at a huge risk of being sued out of existence. Even if automated cars are one hundred times safer than the average human driver, the lawyers will still pounce on the company that makes these for a huge amount on the first accident involving one. And given the way juries often work, they'd likely win.

    That is the trouble with new technologies. The legal system often demands they not just be better, but that they be perfect.

  43. Bad robot drivers by tjwhaynes · · Score: 4

    Will the move to automated driving systems make our journeys out on the highways any better though? Will we end up leaning out of the window and yelling "Stupid MS Driver"? Will we have robots giving us the finger (arm, apendage, tentacle if bioengineering gets going) as they overtake us on the hard shoulder? Will people hack their robot driver to go faster, park on rear-bumper doing 100mph or cut more corners in an effort to avoid traffic lights/ pedestrians/ the police? Will we be attacked with a denial of driving attack by some script kiddie? Or worse, have a UCITA-like end-of-license removal where the originator of the driving OS produces a new version and wants us to upgrade? Stay tuned ... I like the look of the bicycle personally :-)

    Cheers,

    Wow, and people laughed when Kitt the talking car was driving Michael Knight around while he slept! We have arrived people!

    Michael, I have some bad news.

    What is it Klaus? Are we running behind?

    No, but I did hit two pedestrians and drove through a corn field.

    But we aren't running behind.

    No.

    Good then.
