That sucks man. If it's any consolation I'm sure he is happy knowing that others appreciate the knowledge he shared.

From what I can tell from the article it sounds like a woman turned left in front of him. Hopefully this incident will raise awareness for others when they come across a similar situation. Most motorists are looking specifically for cars, motorcycles and especially bicycles are sometimes hidden in plain sight. I've had it happen to me, without incident though. It typically ends with some very close eye contact between the individuals involved and the resposes can vary greatly. Be careful.
