Heyas,
There was a website a while a go where you could go a vent some steam when someone on the road pissed you off.
That website closed down, and now a new improved one has been setup.
http://www.ratetheplate.com.au/
Looks to be much better than the old one, take a look.
My number plate doesn't register anything on there yet, so thats a good start
Did a search, nobody has mentioned this yet so don't flame me thread patrol.
