A human driving a car.

I agree with you that sometimes non-natural situations are easier and can absolutely be better, but the point of bringing up humans is generally to show that it demonstrably is possible to do at least as well as humans, with humans as an existence proof.

But that it might well take too long and cost too much to get there, and that it might well in the end be cheaper and better to use additional types of sensors is a good point.
