That's fair. I was likely remembering that there were two sensors, since there's one for the pilot and one for the copilot, but not remembering that only one of them was in use.

The other lessons worth noting are that 1) you need to give the human some indicator that something's wrong, and 2) you need to give the human some way of overriding the system.

Agreed, mostly. We do have to be careful about how the vehicle disengages and comes to a safe stop, or else we risk repeating the incident where Cruise hit a pedestrian, then pulled to the side of the road while dragging the pedestrian under the vehicle.
