Driver tried changing lanes on a roundabout and tried to drive into the side of me. He then proceeded to gesticulate giving the v sign and other obscene and odd gestures, letting people out of side roads (despite being so impatient to try causing an accident), then proceeded to drive in excess of the speed limit. Caught up later in traffic and I noted he performed more impatient moves by pulling out in front of another car on a round about. Don't know what was wrong with this driver.
Maybe the bloke in the lane next to him on the roundabout was a prick ? .
