> A computer driven car cannot do these things ( This is not true - a computer driven car can do many of these things, moreover - a regular car already does many of these things, such as detecting low traction in rain, ice, etc. Moreover, you are describing Batman - the peak of human condition. Regular human is capable of noticing those things, but more often than not won't notice them because he's distracted by a quarrel with his boss/wife, is thinking about Roman empire and sometimes even browsing his phone. For most people, driving is an automatic lizard-brain activity, and they don't meticulously calculate the wetness of the pavement, the translucency of the air and other conditions to figure out the best speed and trajectory. They just drive by the seat of their pants and hope it'll be ok. > they're pretty slow compared to a human driver. They're "pretty slow" what? Do you mean they have slower than human reaction times? I would rather disbelieve this without a documental proof. Or you mean they are moving slower? Then I would totally believe it, and it's easy to explain - if they move faster and something happens, they'd be sued much more readily in this situation. It's better to slow down than to risk the blowback, even if the car won't be at fault, the speed will always be taken as a measure of guilt. > The context matters to the reaction, because if you see a something that you know it is not going to hurt your car in any way, you have no reason to slam on the brakes No human can't make such kind of decisions in the 0.2s they need to be made. If you notice something jumping at you unexpectedly, you either slam the brakes (and then it turns out it was just a plastic bag blown by the wind, and nothing happens) or you fail to slam the brakes and pray to the Almighty that it would be the plastic bag and not something worse. Context doesn't work in humans in those kinds of timeframes, it's just not enough time. If I ever happen to be in the place of the plastic bag, I'd rather take faster slamming than slower "context", and more potentially unnecessary caution than more accidents.
