the last cyclist death in boston happened the same way, like 5 or so years ago. Some woman was commuting, wearing a helmet, 100% in the right, and got doored by a cab, and couldn't recover, fell out into the road and a city bus ran over her head.
Boston cabbies are possibly the worst thing I've ever experienced. Like 4 years there, and I'm so glad I don't have to deal with them on a regular basis anymore.
This poor guy, just riding his bike, picking up the slack for every meathead driving a fossil fuel box, and this is what happens. So depressing. If there's a memorial ride, I'd really like to try to make it back up to boston.
