Yes, because depending on the situation, the car could be upside down, sideways, with half a side torn off, fire, smoke, flashing lights, flares, temporary barriers, humans both standing and lying, with bits of car everywhere. In the rain or snow, at dusk or with low sun angle. Or maybe the car is actually fine but just in an unusual place, but is covered in decals, high-contrast markings and equipment (eg a police car) that confuse the model just enough astray to enter a dangerous situation. You can't train an AI for every combination of that. Hell, sometimes humans can't assemble a mental model of the situation in time to take safe action.
