wow everyone here has got great ideas, and i take no offense if you guys don't like my idea. how about a tank drive kind of system, two pedals, one on the left other on the right and each control its respectable side of the cart. (right controls right side wheels, vice versa). another parking brake kind of pedal can control forward/reverse drive. the problem i see here is this system is highly custom configuration and might cost big bucks. nevertheless its an idea! not very detail im afraid though haha. i wish the best of luck and recovery to you, your son and your family!
