It's been 2 years but they made us wear the big ol reflective number on the bag and a big sharp licence plate on our bike. Sharp corners and all, the thing was the size of an automobile plate. I refused to ever put the reflective number on my bag because I do not know any other private working citizen that needs to do such a thing while they are working.
The guy that got hit was William Spring, I think he had something to do with the schoolboard. It's an easy story to find on the net. The doctors had to put him into a coma for some reason ot other, but the press claimed that it was the offduty messenger that did that to him.
