Well, again, in Vancouver, I live on a bike route, held up by our local city council ans one of the busiest bike routes in the city as it provides the main path from the downtown core to the suburb to the south of us. The city has very carefully defined these side streets as bike routes they've re-arranged the stop signs so that cars who's path crosses them must stop before crossing the bike route EXCEPT where they've replace the stop signs with a traffic calming circle. I live near one of those. Those intersections are supposed to be handled as an unmarked 4 way stop. They've also posted a 30 Kmph speed limit on the bike routes where the rest of the city is 50 Kmph. So what do I see at this intersection where there's a posted speed limit and it should be treated as an unmarked 4 way stop?
The bicycles ignore the speed limit, easy to do near my house since there's a downhill grade. In fact, the cyclists are pedalling for all their worth to see how fas they can go. Then they hit the traffic calming circle. Since every other cross street has a stop sign they just carry on as if there was a stop sign there so the cyclists pay no attention to the proper right of way rules. Saw a lovely pile up last year when there was a bit of frost on the road. There was no way for the cyclists to control their bicycles as they went around the traffic calming circle and they ended up in a tangled mass at the base of a street tree. They probably wouldn't have crashed if they'd kept to the speed limit.
My point is that the majority of cyclists do not respect the rules of the road because they have no requirement to learn them in order to use a bicycle. Even if they do know them because they also have a real drivers license they know that the police department has been told not to enforce traffic laws against bicycles (confirmed by polling the local community police offices who have stated that the bike route speed limits are not meant to apply to bicycles).
In other words , why is anyone questioning whether something that a cyclist does is smart or not, or right or not. In most communities they've been given carte blanche to do as they will, when they will, where they will simply on the belief that they'll be saving us from the ravages of green house gases produce by cars. The roadie scholar's attitude about responsibility in bicycle accidents is just another expression of that contempt that the typical cyclist seems to have not only for cars but pedestrians as well.
(@admins: there you go an obviously negative comment with my name on it. Its all the truth, it's how I feel and if you still feel the need to ban me from responding as a AC because I haven't the time or inclination to read all the attempts to defend the counter to these positions than I might still read the site but I'll never bother to respond. If you don't like to see bad news printed in your comments then I hope you'll be happy in your mutual appreciation society but real discourse needs two sides to be meaningful.)
