Coming off the slip road onto the A19 the other day I had an idiot in a C63 swerve his car toward mine. As I joined the main carriageway there was a lorry in the nearside lane, so I and the car behind immediately moved into the outside lane. As I checked my mirror, said C63 had appeared from nowhere onto the tail of the car behind. He pulled alongside me, with absolute rage in his eyes, shouting and screaming whilst pointing at me, he swerved his car twice toward mine whilst we were doing 70! (I dont think my laughing helped, there was no chance he was going to risk damaging what was a very nice car) Absolutely stupid what he did, when I pulled out he wasn't there, there is a slight curve in the road so I've assumed hes come hooning along a stupid speeds and got caught up behind us.
