I'm sure some variant of this has been talked to death, but it's relatively new for me.
I've lived in San Francisco for about 13 years, and cycled for many more than that. I can't say I'm the "perfect cycling citizen", but I'm pretty aware of my surroundings, at least slow down at stopsigns, stop at lights, give pedestrians right-of-way, am courteous, acknowledge other people on the road, etc.
For the last couple of years, however, I've noticed a HUGE growth in the number of cyclists who seem heedless of their surroundings, TAKE right-of-way whether it's theirs or not, zig-zag through intersections without stopping even if there are peds or cars there already, using the street as a kind of personal expression space as they careen downhill in totally unpredictable trajectories, and basically act like they are the only people on the road.
Most of those I see doing this I'd classify in the "hipster" or "fakenger" style - fixies/single-speeds, dickies, tattoos, etc. Not that there's anything wrong with that style, but it has seem to come with this kind of entitled attitude. I see this every day on my way to work and back (Haight/Ashbury neighborhood to downtown San Francisco). I also see it a lot on Valencia Street, which is, of course, Hipster Central.
I can't believe the lack of concern for their surroundings most of these guys (and they are mostly guys, not too many women being this rude) show.
Can anyone tell me what's changed in the last few years (besides the large growth in number of bikes on the streets, and prominence of bike advocacy) to make this happen? I mean, it's like the Keystone Cops On Bikes out there lately. As a cyclist, a pedestrian, and a driver, it's really starting to annoy me.
