Very well done. I was wondering when/if anyone was going to try and do a good racer in flash. So far it looks like you guys are on the right "track" .... ug, that was lame.

I got a constant 21fps which was nice and smooth. I running flash player 8 on intel 4 ghz with a good graphics card (ATI X700).

I think the key at this point is going to be details, both in physics and in the overall graphics of the track and cars. Having a few car models, each with thier own distinct and subtle characteristics would be a nice touch. I am sure the final track will come complete with rails and detailed scenery, which will also add a great deal. Like someone else mentioned, for the physics feeling a "snap" when you come out of a turn would be cool.

Keep up the great work guys.
