If teens were smart (which as a group, like any group, they aren't), they would limit themselves. Forget the safety aspect of it. I know that my driving habits would definitely change with the gas prices as they are. Working my arse off at a terrible job for 1 hour would have gotten me like 1.5 gallons of gas (after taxes, maybe a little over 1 gallon?). Totally not worth flooring it. Heck, I would have carpooled even more than I did.
