What are you saying? Please elaborate.
Some bicyclists are good, have proper lane discipline, signal, obay lights / signs, others don't. Some of the worst cyclists I have ever seen:
-At a signalized crosswalk on a 6 lane road. All four lanes came to a stop for the pedestrian who had activated the overhead flashing lights (eg: it was obvious all traffic had stopped for a pedestrian). I was in the curb lane on the ped's destination side of the road. She was in front of my car and I happened to notice in my right mirror Lance Armstrong coming up the gutter at full speed, oblivious to the overhead flashing lights, and lineup of stopped cars. I sounded the horn, which startled the pedestrian, but cause her to stop and not step in front of the bike. I should have had the passenger deploy their door.
-One 3 way stop I used to go through a lot. Curb lane was RIGHT TURN ONLY, inside lane was straight lane. Bicycles would continuously run the stop sign going straight in the gutter of the curb lane. WTF? How can bicycles complain about being hooked if they pass turning traffic in a turn only lane that all have their signals on? The vehicles don't expect someone to be passing illegally like this. If they want to pass going straight, they should split the lanes. Bikes talk about "taking the lane". I started "taking the gutter" at this and other intersections. Driving as close to the curb as possible to prevent bikes from trying to pass when I'm trying to turn right.
-Amsterdam, land of the bicycle, at a major intersection pedestrians had a green light. A big sea of pedestrians were crossing the road, when suddenly perpendicular to the pedestrians a bike was going against the signal, ringing his bell "DING DING DING DING" plowing through pedestrians that had the right of way.
To me, carefully crossing against a signal (slow, look, proceed), and driving on the sidewalk aren't as bad as this. Unfortunately there's a lot of bad apples that give the few good bicyclists a bad name. I will respect bicyclists if they respect other people.
