Great points. It would make perfect sense to have two baselines: One of a few cm for nearby objects and one car-width for good depth resolution of distant objects (which humans can't do, but humans have much better world models than computers, so better depth perception on the part of computers might close that gap a bit.) I also think lidar or radar will always be necessary. The Tesla fatality last week happened because a big white truck pulled out in front of the car. With a big blank surface, stereo pixel correlation is impossible, but it's trivial for lidar or radar to read such surfaces.
