I was on a race track in my Porsche 2 weeks before GBS hit. I know what you mean about driving. Five years later, and still in the quadriplegic class, I drive. No adaptive devices whatsoever. Unlike me, your hands an arms aren't an issue, or present any diffaculties, so I will take that part out of the responce, and concentrate on the feet. With a manual shift, that's also controlled by the hand, so what's left? Three simple pedals. Each with a in and out motion. You don't need feel or that much input with the feet to preform those motions. Start by sitting in a chair, stick legs straight out, and lower onto your heals like in a driving position and move your feet as if driving. Find the range your feet work best in. Often times a simple seat adjustment will put you in a working range that gets the job done. Should that prove a bit tough, take your heal off the ground and do pedal motions using upper leg muscles. It's just in and out. Switch from gas to brake and back. Your shoe will take away from some of that foot drop also. The backside that hits your upper heal area acts as a doorstop in a way. So there is really very little you have to overcome here. If you can get by without aids in everything else but driving, then don't use them just for driving. Repitition is good for the fine muscles in the feet. Might feel ackward at first. Same with supports. I've done both. Now, I assumed that having a brace for walking also included the foot drop issue, like mine did. AFO's. Ankle Foot Orthodics. Endurence is something you already know or could find out easiely enough. How long do you last now?
