It's hard to know exactly what transpired during the altercation at the Critical Mass event this weekend, accounts seems to vary depending on who is talking. I did enjoy reading the driver's point of view however:
While a some cyclists I’ve spoken with have written Mark off as another indignant road-hog, Mark says he actually used to be a bike commuter when he lived in Seattle a few years ago. “I sympathize with [cyclists’] cause. I ride bikes too. I’m a liberal hippie democrat,” he says, adding “I’m gay, the person with me was a lesbian and we were a attacked by eco-terrorists. It’s the most Seattle thing that could have happened.
