For me, no, not usually, especially on 25 mph roads. There are plenty of bikers though who don't like to follow basic traffic signals, so that having to slow down and pass them once, on a busy road full of traffic, turns into having to slow down and pass them 3 or 4 times. Mainly because a lot of bikers in my town don't feel that stoplights apply to them. So right after you get past them, you stop at the intersection, to watch the guy slide up, pass everyone that just passed him, then run the light so we all have to do it again. Right or wrong, it's frustrating.
Then there are the ones, who I really hate, who feel stop signs don't apply to them either. There is one intersection, in my neighborhood, on my way home, where I've almost hit probably 8 bikers, because for some reason, they don't feel the stop sign there applies to them. Of course a couple of them, even though I did manage to stop, still felt the need to call me an ******* and flip me off. (I didn't have a stop sign BTW.)
These are really the only times I get ******. I do realize that the millions of bikers out there, these are the few, but the few of them are just like the few of the people who genuinely hate bikes, they are the ones who stand out. Luckily i live in a pretty Bike friendly town. Most of the roads are marked with special bike lanes, so that helps to ease things a lot.
