It sounds harsh but if there were some effective system to report dangerous driving/ road behaviour, I'd seriously consider it. X number strikes/ bad reports about you and you're out, or some other nasty stuff hits the fan. Mostly aimed at NEW drivers. Road users are a community and any community has a right to disapprove of menacing behaviour. If you can't fit in or at least respect fellow motorists, you have no place in that community.
Imagine if you get notified that you were driving in an antisocial/ dangerous manner... u know that people are watching so the onus is on YOU.
I'm tired of having some twit P-plater, a$$hole, hoon etc. (and yes, i am just naming from majority of experience) come close to killing me, my girlfriend and some other poor inncent road user for no seemingly logical reason other than to cause rage and inconvenience to everyone, and literally being able to do nothing about it.
Yeh, system open to abuse and would need a lot of work, but give some power to the real road users and the people who are affected - not just the police i say!
