The same thing happened to me last summer on a busy street in Boston. Fortunately I wasn't going too fast and just barely grazed the car door (having a helmet on didn't hurt either).
Glad you're ok, Brandon. From what I've been able to tell, bikers are ambivalent about bike lanes. At least in Mass., the cyclist is considered a vehicle just like a car and many feel that dedicated bike lanes like the ones we have in Cambridge make motorists forget this. Also, some drivers are unsure of the rules concerning them.
