I imagine that if you walked in the route that cyclists used, even if protected by law, the initial emotional reaction of the cyclists to the walkers would match that of car drivers being slowed down by cyclists.
This happens to other cyclists if the shoulder is too narrow, the cars are too many, and the "real" cyclists are piling up behind the slower, commuter, cyclist.
It's true. Cyclists can be assholes too!
Yep. Guilty as charged. I'm an asshole cyclist. I get used to having the bike lane almost exclusively to myself all winter, then come Spring there is an influx of fair weather riders for a few weeks until they go back to driving. I get a bit frustrated and annoyed with them for sure, especially the all the ones who have no clue what the rules of the road are.
I've nearly been T-boned by cyclists who don't stop to turn on red, nor look for other cyclist legally crossing the intersection in front of them.
I've been nearly hit by an e-biker who blasted out of the shadows from the wrong-way side walk across the crosswalk while I was turning left (he nearly got hit by a car at the same time!).
I've been stuck behind folks who had just blasted past me just as the light turned green rather than queuing up.
I've been annoyed by cyclists who go onto the sidewalk to cross in the crosswalk rather than use the bike lane, then move over into the bike lane halfway through the intersection without warning, making it very hard to figure out WTF rules they think they are following, or how they think the queue is supposed to work.
I've had runners going the wrong way in the bike lane refuse to go onto the sidewalk (a darn nice one at that) and force me to go into traffic to avoid them.
While none of that justifies some of my cycling assholery, I think it does explain some of it.
