In CA there are no hard rules on what body parts you need to use to operate your vehicle. I looked at this when having to drive with my RH leg in a cast. I threw it up on the bench of the auto transmissin pickup truck and used my left to operate.

I'd encourage you to get creative and also do more research what modifications you can do to the car and your body (prosthetics) to make it happen. Especially if you have the means.

I do recall in Europe, where I grew up in the 70s when there were a lot of amputees from WW2, cars were usually heavily modified to keep these guys driving. Hand controls to replace pedals for example. I once read that driving is super satisfying for handicapped people because they can participate in moving around normally at last.

All the best!
