Chap failed to give way at a round about.
When I shook my head at him he sped around me, screeched to a halt in a cloud of smoke, got out and then started ranting at me. He accused me of "cutting him up". I calmly explained it was a roundabout. He got back in his machine and vacated the scene.
I can only hope next time he notices that it's a round about.
Aggresive idiot, driving on pavements, throwing cans out of car at cyclists and trying to knock them over in solihull.
