    Bees do this little dance that tells the other bees where the flowers are. But algorithmically that's probably nowhere near as sophisticated as visual perception. For a smart car sensor to have true depth perception - not radar ping ping ping - it would need two separate cameras and the brains required to process parallax virtually instantly across the field of view. Assuming it could accomplish this then it would need further brains to interpret this processed depth perception.

    Maybe at that point the car would ready to follow a small set of decision rules. But we and other animals have visual perception hard-wired. It happens "in hardware" in the background - we take it for granted while the "software" side of our thinking controls the vehicle. The next time you're in a self-driving car keep in mind that compared to you it's barreling forward in world of darkness collecting impulses from a suite of widgets.

    I think you are making this more complicated than it is. Algorhythm shmalgorhythm. I could argue your "evolution vs algorhythms" argument is irrelevant to the issue at hand (safe self-driving cars). No you cant put a value on life. Yes people will die. Yes in the not too distant future, self-driving cars will be safer than traditional cars(IMHO of course). Having said that, I think it will probably be 20-30 years (maybe even 38.26) until I bought one. But that is just around the corner. Regards and good read!

    Would you mind making such an argument? I realize it's easy to be impressed by modern technology cuz of smart phones and computer generated special effects in movies. But these were easy problems for which the answers were already known - all that was needed was the for the hardware to evolve to the point where the implementation of these answers became practical. The answers for the problems of self-driving cars are not dependent on the evolution of hardware - they are dependent on the evolution of algorithms.

    What happens when self driving computers (not the car, it's the computer) in their long learning process end up with billions of lines of code? Wouldn't there be conflicts and conundrums with this amount of Shear complexity? Is this the likely result? I know computers can fly and land airliners. Do the approach, flair and land themselves, hold the centerline etc, with only a few things the pilot must do (other than considerable setup and input) such as apply reverse thrust. Is this act more or less difficult for a computer to do than the myriad of different conditions that a car might encounter in its entire life? Will there be point when it will it become necessary to abandon the binary system altogether, the And - Or - Not -Nor- Nand thing and build an actual brain?

    FWIW my view of technology comes from having worked in manufacturing since CNC machines were a novelty and watching cybernetic systems perform fairly sophisticated operations reliably day in and day out (versus commuting on the freeway and seeing fender-benders or worse every day).

    As far as building a brain, I’m going to have to (Shock, Horror!) agree with Loopstick and say that several hundred million years of evolution can’t be just duplicated in a lab. I think the solution is not in making the computer more complicated, it’s in parsing out driving into simple enough components that decisions can be made on a finite number of nested if/then statements.

    I could see this, but it would be the roadway itself that would need to be more controlled in order to have less complex driverless computers. Highways that keep all the variables to a minimum. Currently a road may have occasional spots of black ice on a slight north face. A driverless car must recognize this. Now throw in two other scenarios. A dog suddenly jumps out in front of the car from the right, and at the same time a child approaches out from the left. The car is unable to stop for either, but can make a choice on which to hit. Does it recognize the dog or the kid and does it make the correct choice? The dog being of less value.. This while may prove difficult for a human, I would venture the dog would easily be the one sacraficed with a real person behind the wheel. Not sure about the computer, particularly a less complex one.
    Probably so.. Having computers run CNC is a far far cry from all the unforeseen circumstances that await a driverless car. Would you agree?

    Wow !!

    Trolley problem

    To me the simple problem is that everybody in Michigan knows not to drive over puddles in the Spring cuz beneath the surface of that puddle is a deep chuckhole that will shred your tires and bend your wheels. But to a self-driving car it appears to be an innocent shallow little puddle - assuming it notices the puddle at all. You can have the car "learn" about what Michiganders already know through a neural net - but you don't want to be in the car while it learns those things. :D

    No way, its not really my thing, after all, why did i take my driver's license?
    I really hope it doesn't become a mainstream thing when it catches on, i would prefer it to be a niche thing, for people too rich for their own good.

    I want one so bad. I think the whole word should be forced to use them. Think about it: No rat racing, no drunk driving, no old ladies. If there's an accident it's the manufacturer's insurance responsibility. No more car insurance! I have to drive to the thrift store now (looking for a computer LCD, I'd love to have my car drive me there while I keep reading on the web.

    If they force me into buying a self driver I am going to send it off alone on day trips in order to practice up. If it can get 10kmiles without any harm done I may relax a bit. However I am quite concerned over machines taking over our lives and once accomplished, what will we do with ourselves? At some point what will be left of our mental and physical abilities, will we know how to pour piss out of a boot without the instructions written on the heel?

    I wouldn't worry about it. The only people pushing this are Silicon Valley types who have no clue about the auto industry and cuz they no longer make silicon stuff (moved to China) they gotta get their hands into something else. Many of the developer comments posted to defend the technology in news stories about accidents come from individuals who obviously didn't grow up in a car culture. The fact that they openly refer to what they're doing as "beta testing" indicates a complete disconnect from reality. My guess is if they ever roll these things out in any great number it will be such a huge clusterf* that the whole concept will be shelved.
