i'm with you , i totally understand your viewpoint - in fact i did something pretty much similar to you last year, in that i was the target of a bad and abusive driver (he was in a V35 skyline) and i posted over in their area, instead, some people laughed at me, some people supported me, but most people said that posting up was pointless, like here.
but i too felt that i needed to say something, in case that person was on the forum, that their behaviour was NOT OK (deliberately blocking me off, verbally abusing me etc).
