If it were up to me the driving age would be 21 with all these crazy kids driving around thinking they are Fast and Furious.
Most the Fast and Furious road racers I've seen (and/or had the bad experience of being a passenger with) are well into the mid-to-late 20s or better.
The thing about a 16-year-old behind the wheel is that they are scared stiff to scratch Daddy's car less it be taken away, or scratching their own newly bought car and losing their probational license. One major mishap and either parents or State take away license and they are grounded for life... makes one a bit more cautious.
Of course commenting without yourself having ever experienced that is... well... I won't say the common expression about from where you are talking.
