> they must have to discount stopped objects Well, there are just a lot of them, outside the lane markers, and those never kill you. And while the systems surely try to classify parked cars as well, detection quality isn't under much scrutiny. Then when that one exception is sitting in the lane, good luck, your life depends on a second class feature. Anecdotal evidence suggests that a similar perception vulnerability exists in long distance cyclists who spend many hours on the own road: lanekeeping and pothole/junk avoidance get more and more delegated to subconscious processes which work with eerie (and enticing) reliability. But that "mental autopilot", tuned to the open road, knows the back of cars only as something that pulls away from you, the simple model knows them as something not worth "raising an interrupt" over. Similar learned routines certainly exists with highway driving as well, but when driving, there isn't a class of objects which is routinely there but almost universally not a concern, like backs of cars are for a cyclist. Reports of that cyclist hitting a car parked in the open road always earn a lot of ridicule, but it's not quite as surprising as it seems at first glance (the very majority certainly succeeds at "disengaging" in time, but the exception make the news, same thing in every field)
