Like the others said, the majority of liner's are mature & respect the roads, safety and the laws for good reason.
Everyone knows what can happen when abusing this.
I've cruised with the QLD fraternity recently and all were well behaved and drove sensibly.
When parked we saw 2 180's racing a 33 off the lights and someone could have been hurt in the process.
They're idots, most aren't.
The powers that be (ok, maybe with the exception of one in Melb) soon work out who to hassle and who to let be.
Just be good and enjoy/appreciate your rides, coz one day you'll have kids & drive a boring family car!
