Does anyone know of a phrase or description for someone who pulls out on you causing you to brake/swerve to avoid a collision, then when you beep them has the cheek to give you the finger?

Pulls out in what sense? Should you be driving while performing such an act?

Been the case every time thats happened to me.

Sounds like both a cad and a bounder.

Sounds like a complete MadJohn to me.

A right c.u.nt.?

Some good suggestions, but I wondered if there was a specific word or phrase. If I had to make one up on the spot I would call them a 'doublecunt'.

I think you should all try driving in Doha! Any sort of move is alright, undertaking on slip roads, never use your indicators, driving on the wrong side of the road all in massive powerful car that you can’t drive. At all times you need to drive whilst using your phone as well not hands free though they would be far too safe held up right in front of your face whilst weaving through traffic at high speed! Oh and your kids don’t need car seats they stand, hang out of the window, sit on your knee whilst you drive like someone who has won a competition to drive a car simulator for the first time.

that's the best I have ever heard that should be in ViZ
