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

Mainly because it's pretty obvious that using calm reason is likely to be more successful than
'just screaming like a mentaloid',
isn't it? Do you actually need YouTube helmet cam vids to guide you on this? I don't think you really do.

Except often when anus clenchingly close passes or other acts of pointless aggression happen it gives a massive shot of a very powerful drug into the system which takes a lot of conscious effort & discipline to override especially when that person reacts with such disdain at first & you see them again up the road so you're already in a kind of attack mode.

We've evolved to get angry in the face of aggression or to run from it so that coupled with adrenaline is why a lot of people lose their shit. Especially if it's not the first act of aggression against you in the day.

It's perhaps worth mentioning that calm reasoned logic doesn't always work. It rather largely depends on who you are dealing with. There are many psychological principals at work in any confrontation or encounter. Obviously myself and other cyclists are not such experts at dealing with people who recklessly endanger our lives as you, so for us who have a tendency to be a little hot headed, this video can be a useful reminder to make the effort to try to remain very calm while every instinct in your body is screaming attack/defend/shout/run! seemingly simultaneously.

As far as results go, I personally think she is far less likely to do it again than if she had been completely unchallenged or had been screamed at & not because she thought it was wrong but because she won't want a repeat of that experience but I guess we can't know for sure unless she turns up again on youtube.

Also what Scilly Suffolk said. Although attempting, on top of everything, to explain in a coherent way that the average driver can understand, why cyclists take primary might be a wish too far.
