Shawn McInerney (MooseMouse Media) has launched a public beta of his browser-based multiplayer racing and stunt driving game Smash Da Gas (Unity plugin required).

While a variety of conventional racetracks are included, the real standouts are the Freestyle Hangout Parks, which are basically oversized playgrounds for tiny cars. Even when you don't have any particular objective in mind, it's fun to cruise around, climb steep hills, and perform mid-air stunts after launching yourself off of ramps. I bet it's even better if you can get a few friends to join in!

McInerney notes that additional cars, tracks, and customization features will be added in future updates.
