> When was the last bridge you saw without a barrier to prevent going off the edge? That's a disingenuous question. Many bridges have wooden guards that will prevent you from going off if you make a small mistake, but not a large one. > What makes you think a vehicle vision system will handle "blinded by sun" any worse than humans already do? Humans can move their head, and block the sun with a hand, hat, or sunshade in the car. Humans have two eyes so if one is obstructed, the other may still get good vision. > so being blinded by the sun isn't going to cause it to swerve wildly off course and off the bridge - it can continue to use the data it had before being blinded (just as you do). Unless it's an incredibly well-trained AI, it may mistake lens flare for oncoming traffic, or a pedestrian. Car AI is not at the point where it has common sense to assume that lens flare is incorrect information.
