No I don't drift, and I certainly didn't on the 6 mile drive home
Even thinking about all the turns I made, I'd say there was a relatively even balance of left and right turns. All 4 wheels were spotless when I left the car detail place.
And like I said before, I actually like the way a BMW wheel covered in break dust looks - it's like a second badge, of owning a BMW. I'm just curious why front-right had none and front-left had a significant amount.
