well what can you expect? another thing which builds up some frustration inside:
when you are at a t junction and there is a queue of traffic and the bloke in his company car speeds up to block you, which makes me wind down my window and very calmly

ask him where he thinks he's going? he's now blocking me, but he suddenly has tunnel vision.
notice how it's always a 'he' women are generally much more kind :P
