So, this is for 100% automated cabs. There would be no driver controls whatsoever in these. That way you can use every seat for a passenger. But there is a federal requirement for a brake pedal. This means despite there being no steering wheel, a brake pedal would still be present. But why? There’s a whole bunch of extra hardware for the pedal, and it will never actually be used in normal operation. So that regulation needs to be removed if there are no other human controls to enable robot.

I don’t have an opinion for or against robot cabs. Just explaining what it’s going on here.
