Ok...so this has happened to me 2 separate times now...which is pretty annoying. I ride in the morning peak hour to work each morn, on a dual carriageway motorway (2 lanes each way...Western Freeway in Brisbane)...anyway, traffic is pretty gnarley, generally speaking there is always a 5km grid lock as you get to the city (roundabout bottleneck). It's only 2 lanes, I often lane filter (or 'split'...but only if traffic is going say 40km/hr or less), I split up the left hand side on the edge usually (which is a small edge - say about 50cm wide, with either a drop and grass/gravel or guard rail), as often if you go up the middle it is a bit tricky as people sometimes change lanes or drift over and trucks/buses take up most of their lane. I know most people say the centre is much better for splitting than the edge because on the edge people pull off and open doors and stuff but this is a freeway and there are no exits in the last 4 km to the city and practically no edge big enough for a car to go on, so that's why I do that. Anyway, a few weeks ago I was riding up the LHS edge past a whole heap of cars moving extremely slow, went to lane split up between a guard rail and a B double truck - plenty of room truck going at a walking pace, the truck driver quickly swerved his steering wheel and aimed his truck directly in my path to block me off (or crush me against the guard rail - undecided). Luckily I jammed my brakes on because at first I thought the truck might have just been a little distracted or unintentionally doing it but if I hadn't of pulled out and backed off when I did I would probably not be here typing this now. Later when I got back into a normal lane behind him and finally got past the normal way he was yelling out the window at me. Fair enough, some people get angry as they see you 'jumping the queue' etc, have a quick yell out your window or something but don't try and injure or kill me for it. This exact scenario also happened to me again since this incident, with a double dump truck, only difference was this time when I got past him he was laughing. So either these truckies were angry at me for trying to zip past, bored and wanted a laugh, or trying to teach me a lesson because they have too many near misses with motorcycle riders and want us to stop?? I'm almost at the stage where if I see a truck I am very reluctant to go around it on the edge, and should either wait behind it or go through the centre of the 2 lanes (as obviously it can't ram me if there is an innocent passenger car in the 2nd lane).
