anecdotally, i can't even remember the last time i saw a bicyclist stop at a stop sign. even the guys in their $10k road bikes and full outfits, who ostensibly take bicyclig VERY seriously, just blow through stop signs like they weren't even there. sometimes even stop LIGHTS if it's a t-stop. especially when they're riding in their large groups. and sometimes they even ride on the wrong side of the road (LOL) i live…
If we're going anecdotes, I can't remember the last time I saw a car stop at a stop sign either. http://www.cyclelicio.us/2013/stop-sign-compliance-temecula-...
where I live, anyone who pays attention realizes that most bicyclists are either casual, ignorant weekend riders or very serious road bikers who just simply don't give two shits about the law. commuters who follow the law are VERY rare.
