Game Idea Driving Simulation Scanning

I have played Flatout 2 last hours. This game will never get old. And I've got one thing. Everyone is making awesome car controllers with a lot of physics simulation inside. But what if just scan real car during driving. Put gyroscope on wheels and car body. Then just use scanned data to put colliders in right position. It like a precalculated physics in games will always look more awesome.
