I got hit from behind by a BSM driving instructor this morning whilst riding in to work. We exchanged details after a few heated words (apparently it was my fault for breaking). It wasn't until I got to work that I looked at the piece of paper the bloke had given me - details on one side and on the other were printed the words "your BSM driving instructor called" - made me chuckle. Luckily no damage as far as I can tell.
