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.
Yeah this game was great... I must have played it after other Sonic games had come out. I never knew this was his first appearance. Such a cool piece of history!
Did the car have windshield wipers that you had to turn on when you got mud on the windshield or am I mixing this up with a different game?
I would imagine so considering the fact that the picture posted has muddy windshield and windahield wipers on action
edit: yeah does have that feature! I tried the game on archive.org it's pretty fun
