> Yes, I do remember when Uber killed a pedestrian. A pedestrian that the car didn't see. The car did see the pedestrian. It was unable to correctly identify it as pedestrian initially. And instead of taking the pessimistic path of 'something unknown moving toward roadway, so I brake now' it had that portion disabled in favor of 'safety driver take over.' Reason being, as it came out, that these types of events are so common it would be wholly infeasible to attempt a 'driverless' solution without disabling the emergency braking routine. > lane markings are damaged, you're going to have a bad time no matter what size vehicle you're in. That's true. But it's not a problem humans have. In a Tesla (or whatever, not picking on them specifically), you can probably stop in a reasonable distance, and if you don't, you probably aren't going to kill scores of people. With a semi-truck, stopping distance is greatly increased. So, you need the ability to see farther up the road. If there's traffic in front of you, you obviously can't see lane markings 200 yards up the street. There's just so many variables. What if the road's wet and the lane markings end and the computer thinks it needs to slam on the brakes? I guess jack-knifing the trailer in the middle of busy highway is NBD, because that's what the computer was supposed to do. I won't share the road with such a contraption.
