I had about the same experience with cars. Where I live there are way too many loose dirt roads, so power sliding on the dirt is way too easy... in high school we used to find empty streets to do it on.
When I was actually in a situation that involved my car getting hit by an idiot and losing traction and heading directly towards some house, previous experience kicked in and I just slid a few feet but didn't lose control and didn't hit anything.
I'd love to get a dirt bike and practice on it... there's definitely enough dirt around here to ride on lol. Also some dunes nearby and a few beaches.
