I have seen one of those armless people cars.
They're fitted with all sorts nifty gadgets that change the way the car handles.
A steering wheel that you can operate with your knees, pedals adjusted so they're closer to your feet etc.
The same place also had a car that was drivable without using your legs (shfiters on the steering wheel etc.) .
Those were BMW's they had for sale but you'd have to either get used to the weird controls or have them returned to their original state.
