I saw an article on a new independently developed racing game for the Android crew - Rivals Masters

Appears there is a decent selection of cars. Gameplay is decidedly arcade-like - an endless scroll. YMMV. Appears to be an independent guy developing the game rather than typical Evil Corp conglomerate. I can cheer for the Indy guys to succeed. I'm not touting it, and can't vouch for it as I'm on iOS - simply posting news on a new (to me) racing game.
