It's a minigame contained within the 1995 game "Penn & Teller's Smoke and Mirrors", which was planned for Sega CD but never released.
Your task is to drive a bus from Tuscon, Arizona to Las Vegas. The bus's maximum speed is 45 mph and it constantly veers to the right, so you can't leave. There is no scenery.
Oh, I forgot to mention the trip takes 8 hours and the game can't be paused. If you make it to the end, you get 1 point. If you veer off the road, you are towed back to Tuscon in real time.
