Age has a massive part to do with driving skill
I have had an e36 M3 and a cam'd chipped race catted e46 M3 with 370ish bhp and used to drive them hard, drifting corners etc didn't phase me nor did stupid speeds(detristricted), throw into that several performance bikes zx10r ect and one could say I had some experience and very fast reactions.
Was a good driver? Well I had some skill but that didn't make me a good driver
Now just 3 years older, engaged to the women I love who is 6 months pregnant and NOW I would say I was a good driver.
80mph is where I stop on a clear motorway, I leave double the required braking distance I pride myself in smooth driving with loads of road planning to make good fluid progress without braking all the time (the misses hates the belt pulling into her bump).
I enjoy driveing so much more, the old Range Rover is fast enough and uber comfey and safe for my presious cargo.
Age brings a different mind set,
young: good driving = handling at speed, controlling crazy slides etc.
Old: good driving = smooth safe driving, and the avoidance of hairy situations so you don't need to mange anything
LOL man I sound old now
