In reply to Kemics:
> I'm cycling to work and there's one side of the road closed and temporary lights. I'm cycling through the road works close to the cones. I realise I should have been riding defensively in the middle of the lane. However, a guy passes me and as it's so tight he clips my handle bars with his mirror. I wobble but stay on the bike. He pulls in to a petrol station a couple hundred meters up the road. I cycle up to him and asked if he realised he hit me. I'm not confrontational or aggressive. He is a scrotty chav (if you can excuse some bias) and immediately starts giving it large "f*ck you, I'll knock you out now or f*cking ram you off next time" etc. I'm cycling to work so realise talking is a waste of time so cycle off.
> I got his registration. Should I report it to the police? Will they/can they do anything? I feel like they'll be too busy solving murders etc to have time for such petty stuff. But just feels like it wasn't really acceptable. thoughts?
Report him anyway.
Chances are they won't do anything without any evidence (they often ignore it even with evidence, but that depends on the will of your particular constabulary or individual officer to take traffic offences seriously). But even if they just note his number plate in a report, if he's reported again in future then he'll have a history.
It's not a petty crime, the guy is a potential killer. And the police need to be put under pressure to take these things seriously.
