As for what has changed, there are other things, but distractions in general have definitely gone up (Sat radio, GPS, cell phones, MP3, etc).
As for the young girls.... call me sexist. When I was in HS, the big thing was teenage boy drivers were "worse", and hence cost more to insure, etc. My assertion was that we were BETTER drivers, BUT we let our ego drive us too much, and hance caused more catastrophic crashes. HOWEVER, girls had more FREQUENT accidents, just way lower cost. Backing into the mail man, other parked cars, curbs, shopping carts, etc. My theory was, and 15 years later remains, males have much better spacial relations and just plain understand the physics better (end gross generalization...).
Running yourself off the road at 100 mph is just stupid. Not being able to paralell park is bad driving
Looks like things haven't changed much!
