Ooh ooh he's parked on a white line too. No-one knows what they are. Edge of carriageway on an urban clearway, which means no parking. If it's an urban clearway he'll get a parking ticket. woop.
They were driving over the speed limit and over-taking on the approach to a roundabout? If so, then I think they deserve to get their car smashed to bits - it's the only way some people learn..
Looks like some double white lines are needed there..not that I'm suggesting their absence is justification for what the driver did.
