you don't need a driver's license to drive. I never got a my DL until I was 21 but that didn't stop me from owning several vehicles, drove across country several times and on the job, and did for hire Ryder truck shuttle work before I was even 16, all without a DL. I think I even drove in Mexico (yikes!) and of course, a lot of drinkin and drivin.
So don't think strict driving rules for teens will stop teens from driving, just the ones that listen to authority.
