Cyclists and drivers ignoring the rules of the road both make me very angry.
I live in Massachusetts, which is one of the states that specifies that cyclists must ride single file. I found it interesting that quint41 complained about cyclists riding 2 or 3 abreast, yet when I checked the vehicle code for her state (Connecticut) that it specified that cyclists are allowed to ride 2 abreast.
Cyclists taking up the driving lane by riding in bunches are not riding safely and certainly not sharing the road. Unfortunately I've seen many club riders who seem to think they are exempt from the laws.
Of course, that's not always true. I was doing a ride along the New Hampshire coast last spring when I was passed by two groups of cyclists. The first group was spread across the road, blocking traffic. Bad. The second group was riding two abreast (as is allowed by New Hampshire vehicle code), but as they approached me, they also recognized that there was a car behind them. They immediately fell into a single file, passed me, and allowed the car to pass them before doubling up again. Nice.
But - we do have the right, and we should, take up as much of the road as necessary to be safe. I won't ride on the very edge of the road. I feel that is unsafe both from a road surface point of view and from a motorist point of view. If I'm riding on the edge, motorists don't realize they need to pull out to safely pass me. My tendency is to ride 1/4 to 1/3 of the way into the driving lane. Exception to that is if I'm riding on a road that has paved shoulders. I'm quite happy to ride on the shoulders then. Maybe I shouldn't as a vehicle, but that makes sense to me.
I always stop at stop signs and at lights. And I will not pull out in front of a moving car. (Maybe I'm a little more leary of cars after my non-car-related bicycle crash a few years back, but I don't think so...).
Funny thing is, as I commute to work (in the warmer & lighter parts of the year) and stand waiting for traffic to clear, drivers will often stop for me. I still only proceed if I think it's safe. But given that I live in a state that (seems to be, or) is known for inconsiderate drivers, I find that when I respect the drivers that they also respect me (and my bike).
