While it might be possible to remotely control a production car, cars now are safe enough that you’d need to have a lot of systems fail in order to ensure that an accident would be fatal. Things like, all the crumple zones not working as intended, airbags not going off, seat belts not locking properly, all at once. Or you could, I dunno, design the car so that the doors were only controlled electronically, and then ensure that if there was a fire or the car was submerged, the electronics failed (e.g., Teslas).
