I am a retired letter carrier. I had to leave due to my right foot. I had a mounted route and driving was too painfull. 5 years before I left I started to drive with my left foot. It was awkward at first, but after a few days, it felt natural. I also have trouble sewing with the right foot. I usually use the heal to control the peddle. I have tried the left foot, but control is quite different than a vehicle. I do know with a little effort, the left foot will perform as well as the right.
