First of all, it sucks that there was a car in the wrong lane and that you got some minor injuries. However, this phrase in your post kind of grabbed me: "I could not see the lane I was turning into..."

Ummm, if you can't see where you're going, is it really safe to go there, especially going so fast that you fly over your handlebars when you need to put on the brakes? There could have been a disabled vehicle there, a tree branch, an accident scene, or even the Loch Ness monster. Yes, it sucks that there was a car doing something unusual and illegal, but shouldn't you be on the lookout for the unusual and illegal while biking around Boston?
