I also someimes just sit in teh queue. Allows me to shake my head at RLJs (:-)).
Did have a conversation with a guy who pulled up behind me then pushed passed while waiting at lights (him on pseudo mtb).
Me: I wouldn't sit there mate, he's going left and hasn't seen you.
Him: No indictors so he's gong straight on, you can't tell me what to do.
Me: OK fella crack on.
Him: What the **** he just turned left across me, what a ******, did you see that? **** i'm gonna report him etc, etc, etc.
Me: Have a nice day
