Out here in LA, I smile and nod at the guys showing off on some of the more rural canyon routes, typical two-lane roads with minimal "traffic" occuring only in packs, no buildings, cars or pedestrians imediatley on the road, so if you safely pass the packs of traffic then the road ahead is all yours. These are also typicaly the riders that can pull off a wheelie for infinity and even a couple I've seen ride through very mild curves doing one... in other words they know and control their bikes very well, also probabley have driven the piece of road hundreds of times before too. Now the nupties that pull off half-second wheelies while weaving through traffic on the freeway or along Wilshire or Santa Monica blvd... they're skilless idiots in comparison, undoubtedly about to get someone else hurt. I think it was last year that a beamer decided to try and race with a pocket rocket down Santa Monica blvd. at ~4pm, the pocket rocket disapeared with the wind after the beamer plowed through about 100' of sidewalk and through a bus stop... when idiots unite.
