I'm in exactly your same boat. Do all the work on my car myself, only drive a manual, know how my tires will perform on various pavement at various temperatures, wear driving shoes, leave the radio off, etc., because I'm an enthusiast. A few years ago I was teaching my son to drive on slick roads so we were spinning cookies, doing bootlegger turns, and using engine power rather than braking to get out of situations in the county fairgrounds parking lot. There was no one around, nothing to run into, but yet a local officer started circling us on the perimeter lot road, at which point I had my son back off for safety reasons since there was another car in the parking lot. Anyway, he decided to light us up, then threatened my son and myself (because he had a learners permit) with reckless driving charges. And so it is in the US, land of the ignorant when it comes to actually learning how to drive or having the ability to teach our kids how to drive in an abandoned parking lot. I much, much, much prefer Germany in this regard. They really do get it on this front.
