I’d like to direct your attention to this photo:
This is the rear seat of a 1920 Detroit Electric Model 82 Brougham, with the tiller and speed control folded up.
These are the front seats of the same car. Note that there’s no controls up front, only gauges. And, the brake pedal is on the floor.
The early 20th century EVs tended to have a sitting room layout, with the driver in the back seat, so that all occupants of the car could converse. That is, of course, completely horrifying, although these cars did top out at ~25 mph or so.
However, in 2018, there’s a class of vehicle, the FMVSS 500 Low Speed Vehicle, that is designed for four-wheel vehicles under 3000 lbs GVWR (note that the EVs of the period were over 3000 lbs curb weight), with a top speed between 20 and 25 mph.
...as far as I can tell, there’s nothing stopping you from putting the driver in the back.
Enjoy that horrifying thought today!
