He's saying the truth. 8-9 / 10 asshats on bikes don't follow the rules of the road that they are legally required to. Just a few things:
1: don't stop for stop signs... many times not even slowing down, then expecting traffic to magically not hit them. I have personally witnessed several tickets being handed out to them since my city is FINALLY starting to crack down on them, they will even do it right in front of a cop....
2: riding on sidewalks instead of using the apparently wasted bike lanes, and hitting people walking ( you know the ones that belong on the sidewalks ). Happens with different asshats several times a month in my city alone, and I doubt it is a fluke since you see all the other asshattery anywhere you go. Hell because of #1 I have been hit by a stupid ass biker in a fucking crosswalk with the light in MY favor.
3: they observe speed limits worse than 4-wheel car drivers. School zone? Still going as fast as possible, on the sidewalk where they don't belong. They should be ticketed just as if a car was speeding ( this does occasionally happen, just needs to more often).
There you go, took mere minutes to come up with just a few things that 80% of the observed bike riders do to make everyone look down on bike riders. Sucks for the last 10-20% that actually are courteous, but then maybe THEY should start bashing heads of the rest if they want their image to look better.
