basically the Uber vehicle saw something it couldn't identify, then thought it did, then when it was too late decided to give control back to the human? It seems like the same thing could have happened if it was any larger, slower moving object, like a car limping along with a flat tire or road workers putting out cones or COUNTLESS other scenarios. To not have the overarching safety critical rule of "DON'T HIT STUFF" seems negligent. The car should always know its own speed and and stopping distance. If you are traveling at 45 mph and approaching an object going 2 mph and it's not accelerating, when you get to that distance put on the brakes!!! You avoid hitting an unknown object that might be people, a stroller, a construction crew and the worst that happens is you get rear ended in your known object... the car with structure and airbags. Heck, flash brake lights before you actually apply the brakes. Yes, I don't think negligent is too strong a word here, if the article is accurate.
