This is the closest Subject/ topic thing i can think of, because it sort of incorporates traffic riding tips, with a bit of politics and even some rant. I ride every day to school down multi lane main road - 60 to 70 kmh limit if that makes a difference, and when the gap is sufficient, and i think the benefit is great enough, i split to the front. A few days back, i was riding to school, and i was over taken by a bloke on a ducati (absolutely beautiful, tricolore 109 and i proceeded to follow him and keep up - i find it better to let somebody forge ahead and me be in the wake... its somehow easier that way in traffic... anyway, i followed him spitting once or twice, and at one of the final lights, i was going to go down a different line of cars than he was, but a ford seemed to be intent on making the gap to small for me. i felt it was suspicious, so i was content to sit behind her as going around might enrage her. as the lights went, i made my way over to the bus lane and started making good progress again. about two or three sets of lights later, coming up to my turn, this same ford cut across two lanes of peak hour traffic VERY quickly, to be smack bang in front of me. as soon as she stopped (hard, but i left a large gap) she opened her door to stop me splitting. i have never seen this car before and she was PISSED. she yelled some sh** about having a bull bar for me at home, and a few attempeted agressive driving moves later, it was over. my point is, how many people have inexplicable aggression like this? i have half a mind to stop splitting alltogether. would i be in the wrong should she open her door on me- in a clear attempt to knock me off? i feel the ducati might have inadvertently pissed her off, but are there techniques to split/filter with courtesy to car drivers? and do cops come down hard on going far out in the front of the lines at the intersection for bikes?
