Ok we have a huge misunderstanding here of lanesplitting, filtering and lane sharing.
The word lanesplitting or filtering, downunder is the act of, moving forwards between stopped or very slow moving gridlocked traffic.
An act that soon could become an illegal act.
Lanesharing however has always been an illegal act, when moving forward between traffic, on freeways, highways and major roads at speed. Cops in this state have never to my knowledge ever booked anyone on a bike for lanesplitting, unless they were being total squids doing it, ie at speed or not being in total control, rough surfaces etc. Having said that they will book you at the drop of a hat for lanesharing, if there was any real cops out there to do so. But having just said that, I have been known to laneshare, unlike places like the UK, here in Victoria hogging the right hand lane does not draw the police attention, so we often come across mr right sitting in the right hand lane ( our overtaking lane) matching the speed of mr left. Mr left is in the left lane legally and morally correctly even if he wishes to sit on a speed which is 40 kilometers per hour under the posted speed limit. However mr right will sit there and match the speed of mr left for mile after mile after mile. It in itself is an illegel act, but with a lack of real cops, its happening and getting worse, so I will laneshare to get away from mr idiot and all the really pissed off people stuck behind these fools. And should I get pulled over and booked for doing so I will be there in court wanting to know why I got pulled over and not mr right.
