Wishes to ram bicyclists off the road are commonly expressed, and every sweeping generalization is backed up by some anecdotal evidence. MOST of my friends have been hit-and-run by cars at this point (injuries up to a broken arm) and we're not bike punks or teenagers or activists just adults trying to get to work.
Look at the comments in this article too:
"a lot of cyclist do do infuriating, selfish things", "I still find myself enraged at cyclists when I drive", "Get the hell out of my way!", "It becomes enraging when they break traffic laws"
It seems most people behind the wheel of a car, or even bike, become ENRAGED the second they have to tap the breaks a little. People need to relax and see the injurable PEOPLE operating the vehicles around them. Sadly I don't think this article gets to the deeper issue.
