I'd say that my dad is a better driver than me, but to be honest, I think I'm a better driver than my mom. My dad grew up driving cars his entire life starting at 14 and knows everything from the basics to the little specs. My mom doesn't really pay attention as stated in the OP, and tends to be more aggressive and more willing to take risks (if you'll remember the stories I've told about tailgaters).
I haven't been driving long, not really doing so regularly until not long after 17. But the fact that I can drive a two ton refrigerator with wheels (Ford E-350 as my everyday driver) staying away from rumble strips and driving on winding roads of undulating elevations and only eight inches wider kind of helps. I also do my best to abide by speed limits even when cops aren't around. :O
