Douglas Bader taught himself to drive a car with two walking sticks I think, maybe only one!I could have got a new car but I don't like modern cars!
would be well-illegal though.
I have a mate who is a farmer who lost one leg below the knee, he drives an auto with the accelerator on the other side, but he drives a series 1 by using his left foot , the good one, to brake and work the clutch, his "peg" just works the accelerator. When stopping he pushes it out of gear with the lever, while braking. Prolly can't do that so easy with a more modern car!
