I see this too. The driver does not deserve to have a licence. He is local and I have witnessed him doing exactly the same in his lil boy racer car that looks like it should never be fit to be on the roads.
Go and read the highway code and learn how to merge in turn you stupid cow. Getting triggered and very nearly writing off someone's car because they used the empty lane and correctly merged is pathetic. Then at the top of the hill using the left turn only lane to cut up everyone in the lane to go straight on...you need your licence taking off you!
