I don't get in as much seat time since retirement, probably about 12-15,000/year, but that's a guess.
Soon as I got my driver's license I could hardly be pried from behind the wheel. (Actually, before, to be honest...)
From the mid '70s through the late '80s, easily 70K a year.
It was mostly business, time-is-money style, plus road trips.
Then some years commuting & some road trips.
Mid-late '90s, seat time picked back up, about 50K/year, until 2004.
After that, 5 years of a 126-mile/day commute in any weather.
Then it tapered off again to about 40-45K/year, until I retired 18 months ago.

I absolutely love driving, though; hoping to get in a couple of long road trips this year.
