Humans don't use radar or ultrasound sense to drive. If we want cars that drive like humans drive they should use the same senses. For example, in the northern parts of the USA there is snow cover for much of the year and lanes are emergent from flocking without any absolute reference to the actual location of the lanes. The reasons everyone choses the same places to drive are that they see the same environment with the same senses. Even if autonomous driving with radar and ultrasound was made to work if it picks the correct lane position and all the humans pick the wrong new lane position then the car is wrong, not the humans.
