on motorways, duel carriageways, etc... drivers who leave a large enough gap for you to pull out into, you signal to pull over to the next lane, as you pull out they speed up to close the gap up and start flashing and beeping as if you've cut them up. maybe its just me but it a bit frustrating ! why do people do it ? happened to me today on the m40 was a silver vauxhall corsa IIRC. matty.
