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.
It plays amazing too, it really feels like a Sega/Namco game. I play in normal mode because I am not the greatest at racing games and I find it super enjoyable.. The last racing game that interested me was excite truck on Wii and I test a lot of them to find something I like among them.
