I think they should have different levels of licenses. They should make you get a license pefore you do performance mods, to keep kids from wrapping themselves around trees because of lack of experience. Doesn't mean if you have the license you can speed, etc... but lets you do performace mods. You should have to take a test, like the regular one, except it should be harder, to show you are capable of handling a more powerful car. What do you guys think?
