IMHO, AC Propulsion (Tesla Motors) uses AC because a mechanically commutated DC motor that meets the high turn down ratio of a vehicle application is more complex than an electronically commutated AC motor.
Pre autopilot cars have an electric vacuum pump and conventional Brembo brakes. You can faintly hear the pump working when you first get in the car. The autopilot cars have electromechanical brakes. The brakes bring big news, too. Rather than use a vacuum brake booster, Tesla uses an electromechanical brake setup.
