no for me, since a auto cross training lesson will automatically teach you about dynamic car control over the limit at a safe speed, and I think that's the point of the training. It's just an introduction to car dynamics, and in that regard, there's no difference whether you want to drift or grip. I don't think anyone without a clue on what car dynamic is should start drifting right away because there's so much going on. Or challenge himself a lap around south city long in the LX6 for the same reason.
Instead he should develop his skill bit by bit, and the training lesson do just that, breaking down essential skills. When people go learn drifting, they always start by doing donuts and 8 figure slides at slow speed, to learn about balancing the front and rear over the grip limit. And that's something you will naturally learn about when you try to drive fast as well, dedicated drift techniques should not come into play until you are some sort of novice in track driving, or else one might become a drift only driver who can't race.
I understand there is a drift community here but the skills involved in racing is generally much more applicable in a vast situation. One who race will naturally know how to induce or correct a slide, and he just need to do some adjustment so to start drifting, but one who drift won't have experience with threshold braking and maintaining minimal friction under the limit. introducing racing techniques early (even though the user might be orientated to drifting already) would help bringing up a more all rounded individual, which in the end avoid the split in both worlds.
