At first this looked like a left hook, just another impatient prick who wont wait until it is safe to overtake. Then he turned right, so this was presumably a deliberate attempt to intimidate me. Reported to the police.
This idiot had plenty of room to pass, but deliberately came as close as possible to try to scare me. Reported to the police, who took no notice. Thus proving thsat complaints to roadsafe are routinely ignored.
