I've clipped a mirror or two, but not because I couldn't "fit"; sometimes, the cars decide to try to creep in on you. It happened right after I went from my EX250 to the F3; I think the mirror height and sticking-outage is very different between the two. Now that I've adjusted, no new clips. Never caused any damage or even folded in any mirrors, though. Light taps. I also noticed that a lot of the "if you clip a mirror you must pay with your head" people live in areas like San Jose, etc.. ya know.. the cities in which the lanes are wide enough to land freaking jumbo jets on? Splitting in the city and Berkeley (hell, most of the east bay) is crazy and the lanes are tight as all hell. On most days when I'm not in a hurry, I don't even try to split. Especially down messed up tight streets like San Pablo..
