You can do this with a second controller.
- Start a split screen / multiplayer race with 2 players
- On the track selection screen press y (settings)
- Set difficulty to: off (so no cpu players are present)
- Set rounds to: 1
- Drive a round and cross the finish in reverse and get the achievement!!!
(player 2 does not have to move 1 inch and gets a "Project Rub" achievement for free)
