I met a guy like this at the gym. He was in his 50s. He said the best advice his mentor ever gave him when got the chair was - never buy a scooty puff. Workout, train, make yourself use a chair that requires strength. So, he, just like your friend, is capable of all kinds of things. He's totally self-sufficient because he made a choice to do it the hard way initially so that the remainder of his life would be easier. Dude didn't even need a handicap spot. Just one wide enough that he could swing his door open and setup his chair while he was sitting in the driver's seat. Pretty awesome guy.
