Was on a bus earlier that got stuck in a main road because there wasn't
enough room to pass another bus coming in the opposite direction. Both
buses were stuck with queues of cars in either direction.

After a few heated words (nothing offensive I hasten to add), our driver
shouted to the other 'I'm going into Code Red'. Anyone know what code
red is?

I have no idea how they got out of that problem, there was little either
bus could do to get out of it.
