Then why not flip the scheme. Instead of have the human as backup to the machine, make the machine backup the human. Let the human do all the driving and have the robot jump in whenever the human makes a mistake. Telemetry can then record all the situations where the human and the machine disagreed. That should provide all the necessary data, with the benefit of the robot perhaps preventing many accidents.
Of course this is impossible in the real world. Nobody is going to buy a car that will randomly make its own decisions, that will pull the wheel from your hands ever time it thinks you are making an illegal lane change. Want safety? How about a Tesla that is electronically incapable of speeding. Good luck selling that one.
