Please report dangerous drivers to the police - Roadsafe. Report to plod, not just whinge here.

^Sounds like you regret doing that.
I unusually lost my rag with a driver tailgating and hooting me around Newington Green roundabout. Swore at him which I don't usually do then saw he had his kid in the car. Didn't feel good about that. While I think the huge increase in cycling is taming drivers in London significantly the idiots stand out even more.

Had a driver trying to squeeze past a snake of 7 children on Morning Lane at its narrowest. Turning round to see she was on her phone nearly made me lose it; in this case there being 7 kids in front of me made me bite my tongue. But a gesture to the woman did get her to pull over and stop.
