They bring up a good point though. Society has decided that conventional steering systems are within defined failure bounds, assuming a perfectly safe driver of course. So to remove the steering wheel from a Tesla, FSD must be as fault tolerant as steering wheel failure limitations, plus some driver competence metric. Of course that also doesn't take into account the thorny issue of the intersection of safe actions on Tesla FSD actions to human driver actions. FSD has a long way to go.
