There just so happen to be a story in the Sun Sports section today about a golfer on his way to becoming a pro when he was driving a 3 wheel golf cart back in 1974 and had an accident and was paralyzed for life.
This link has info about him, but doesn't mention it was a 3-wheeler, that was in the Sun today but that story is not online yet.
