Can't you guys just look it up somewhere.

It's been over 10 years since this was done, so any beginner programmer already knows exactly how Mario Kart and Top Gear were done.

There are tons of tutorials/resources about game making.
Just because those are for console games makes no difference. Simply translate it to action script.

Besides don't we already have a Flash Kart and a couple of other 3D racing games which look better than this ( I like the engine, but looks like a pixel mess )
