I mention it because many drivers think the triangle indicates how far they should be or could be exercising a tire's tread.

aerobod once again, you are a font of incredible knowledge.
I little googling confirms you are right on this. But, as a side benefit, they do seem to work pretty well as tire rollover indicators also.
I've found that on a performance tire, if you are scrubbing them off, you are probably abusing the tire or the pressures are wrong.
I do love the little smiling Michelin Bibendum triangles. Always enjoy when a manufacturer has a little fun with something like that.
