I think back to myself at 16 and cringe at the thought of me being allowed to drive a car...
Because all three cars were ours, and it occurred on our property, there were no tickets, no police activity, no DMV penalties, nothing -- if my parents hadn't been strict (and thank GOD they were), I could've just kept driving.
I also cringe at the thought of that happening, because I, like a lot of 16 year olds, was really stupid.
