In the recent issue of The Physics Teacher there's some photographs (subscription required) that puzzled the person who sent them in, a set of wavy skidmarks on a back road. Neatly sinusoidal, ending in a donut.
Naturally, I recognized it as the result of someone practicing their drifting, and have let both the submitter and the journal editors know. :)

If you happen to know the mechanics of drifting, and think you could explain them in detail to an interested physicist, use the email in the image and tell them I sent you. :)
