Perhaps the car sensors would have seen the child moving, he was hidden just before he ran out into the road but he probably wasn't hiding waiting to jump out.

Perhaps the car sensors would have seen the child moving, he was hidden just before he ran out into the road but he probably wasn't hiding waiting to jump out. So there's a chance that the cars sensors would spot him. Plus the sensors will be tied to the speed the car is doing so will always attentively watching in the range of where children can come from. Further to this you can plug this kind of data into an autonomous vehicle and train it to avoid kids. Humans will probably never have proper driving simulation testing like pilots do because it's too expensive. So in these extreme events I'm confident that autonomous cars will be better prepared. Perhaps there will still be cases where the child still dies but it will be less.
