"... and it is us."
Cyclists resent motorists because a few of them drive in such hazardous, inattentive fashion.
And motorists resent cyclists because a few of them ride in such hazardous, reckless fashion.
HERE is a story from Seattle: "A bicyclist is accused of plowing into a 6-year old boy who was crossing the street with his father."
The poor kid was in a crosswalk, and doing everything properly.
The cyclist was blasting down the road, ironically right in front of the Pike Place Market, on his "fixed gear bike that has no brakes." He ran a red light and collided with the kid. After the accident, the cyclist, Rafael Aranetal, tried to flee the scene, but witnesses detained him. He was charged with vehicular assault and felony hit and run.
The little boy's jaw was broken in three places, and is now wired shut. The doctors hope they can save his lower teeth. But they say he was lucky; if the impact had been in his temple instead of his jaw, he'd probably be dead now.
If you ride a "fixie" with no brakes on public roads... you are a moron, and no friend to the cycling community.
