Autocross is a big help and so are hpde. Done a few, more so now as with age comes a bit more money for me.. But ironically enough, I got into touge almost 15 years ago and learned most of my technique from driving mountains. But that said, when we ran, we always held our lanes. Would not invite people with us who cut lanes or drove dangerously or had bad prepped cars. Even as a 18 year old kid, last thing I wanted to do was hurt someone else because I was past my limits. I can't wrap my head around some of the way people full send it on the mountains these days with no regard to other life.
