Mod: I did a few searches; I hope this is ok as a new thread. I've gone through a progression from not filtering at all, to doing it a little, then all the time, and have now come full circle in a sense: I filter sometimes, but I assess each situation before making the decision. Some of the things which give me pause include: * If the car at the front of the queue seems like they may "contest" my right to be at the front, I'd rather not be there. I can wind the Spada up fairly fast, but not fast enough to safely drag a loony in any decent car, and if I hold anyone up I'm an inconsiderate driver. * If I don't know the lights well enough to know what order they change in, I'm more likely to hold back. * If I don't quite make it to the front and have to slot in between moving cars, I often feel like there's not enough space around me and I can't create it without further annoying people I've already pushed in front of. * If I'm intelligent about where I choose to filter, I don't need to do it at every set of lights to achieve good results. Choosing my moments strategically I can have both good safety and progress. * If the gap looks tight or awkward, and I fail to negotiate it smoothly, I'll look and feel like a complete idiot. * Sometimes I can tell by looking down the road, or thinking about my route, there's another place a little further on I can make the same gains with less drama. * The more considerate and competent I can appear to other motorists, the safer I feel - they are more likely to be considerate and safe around me. * If the guy at the front is in an SUV, he probably needs to be reminded that my $2000 motorbike is a better city vehicle than his $40,000 oil burner If I had to boil my decision down to a few factors: * Will I hold anyone up by filtering? Can I make it to the front before the lights change, get off ahead of the lead cars, and is the road ahead free of hazards I'd have to slow down for? * Will filtering increase, or at least maintain, the space around me and my safety? * Will I have to wait at the same lights for more than one change if I don't filter? Or am I so chillaxed I don't care? * Is it raining? Bugger sitting around in the rain ... I think people care far less about people filtering when we appear competent, thoughtful and considerate, though there's always going to be the odd crazy. Also, whenever it looks close, I take pains to slow *right* down, put a foot down and cautiously manouver my mirrors past other motorists'. I often bend mine out of the way beforehand to increase clearance. Nothing pisses people off like clipping their mirrors! If you filter sometimes, depending on conditions, what influences your decision?
