I had a ski buddy in the 50's that had a 2-cycle Saab. He liked to park
uphill and coast backward in a forward gear and pop the clutch. Then he had
several reverse gears and one forward.
It reminds me of my favorite episode on "Candid Camera." They had a
beautiful buxom blonde trying to park a big car in a supermarket parking
lot. She was having problems and would ask men to help her park. Well, these
guys would swagger up to help the poor miss out, except, the crew had
reversed the steering somehow......so left was right. It was hilarious.
