I'm a biker and a car driver, and I live in Brisbane, so anyone who lives here knows what the traffic is like.
Given that I only ride with a leather jacket, long pants and lace free biker boots (anyone who turns up at a hospital after binning it while only wearing shorts and thongs should be put at the bottom of the triage list), I understand that it gets really hot out in the sun while in the queue and that lane splitting when the traffic is stopped, while illegal, is understandable.
I had a couple of Brisbane bicycle coppers lane split on me while I was on Roma street just last week...and they caught up with me at every red light (they were all red)...
But lane splitting in moving traffic is a big no no. The danger is immense and since we know that Queenslanders do not use their indicators or look over their shoulders when changing lanes I would be petrified to attempt it in moving traffic.
I watched a guy on some Jap bike splitting down Gympie road the other day, and the P plater in front of me deliberately moved across the lane to tighten up the channel and stop him - the biker just grabbed his mirror and folded it back against his fairing - nice deisgn feature, probably created to stop mirrors being snapped off in minor lay downs...but it was still pretty funny to watch - the biker just kept on cruising.
I split when the traffic is standing and the weather is hot, but I would never dream of touching someone elses car...although I would like to throw a couple of old sparkplugs over my shoulder after passing some donkey who has just thrown a burning cigarette out his window with me behind him.
Have fun all.
