They're both needless and inevitable. Confront people (needlessly) often enough and you'll get into grief.
I'd be fascinated to know what the KSI stats are for people involved rtc's where a link to mobile use has been suspected by the investigating officers versus the KSI stats for road rage incidents.
Allowing anti-social behaviour, and anti-social driving is precisely that, to go unchecked is a recipe for disaster for our communities. And given that "leave it to the police" is about as effective a remedy as a chocolate fireguard is a health and safety measure is it any wonder folk will turn vigilante? It is entirely possible to confront someone assertively and not have that escalate into aggression and violence despite what the naysayers might think.
But then again, the police hereabouts, recognising the problem of anti-social driving is pretty much out of their power to control decided to do something about it and now actively encourage such vigilantism http://www.operationcrackdown.org/ My own experience has been that is it is a bit hit'n'miss, much like my experience of direct interaction with the boys in blue.
