Anyone remember Rad Mobile the first Sonic The Hedgehog game?

Rad Mobile is an arcade Sega racing game from 1991. It was the first appearance of Sonic the Hedgehog... as a windshield ornament! The cars were sprites. Later they released the game retitled Gale Racer for the Sega Saturn with polygon cars.

I recently played the game and found it really challenge to rank high. The game has 20 levels starting in Los Angeles and ending in New York.
