You left-handers have difficulty driving/power shifting standard?

When I worked at the local speed shop as a kid, there was this black dude everybody knew and liked. He had one arm. His left. He had a 69 SS396/375 Chevelle. You guessed it. 4 speed car. That guy to this day was the fastest shiftin fool I ever saw with a 4 speed. We still talk about him. Nobody knows how he did it but he sure did.
