I've got nothing against anyone doing it, but it's something I've never done in my current (and first RWD) car. It just pains me to think of all the unnecessary load and wear on everything.
I know it's not a rational analogy, but to me it makes as much sense as slapping a pet dog or something that you'd otherwise care very much for, for no real reason.
My brother got an awesome 200SX that had been cared for, and it was his first RWD car too, and he did shit like this all the time if there were any mates in view, and a year down the line it was starting to show the wear.
Not moaning, or holier-than-thou'ing, just don't see the appeal. But then, there's probably lots of things I enjoy that others wouldn't see the appeal in, and they have no right to interfere, so each to their own
