I know, I know, there have already been hundreds of topics on lane splitting/filtering...but I have searched, read through about 75 different threads, also googled and not found what I am looking for, so posting away! I have recently started lane splitting/filtering through peak hour traffic on the freeway. This is the Western Freeway in Brisbane, so only 2 lanes, and you are separated from the other direction traffic by either grass median or concrete barrier. Questions: 1. In utter grid lock (i.e. both lanes jammed, all traffic under 30km/hr), if you saw a cop in the traffic like a paddy wagon while splitting, would you pull in and stop/behave yourself? Or just keep splitting past it given it is stuck in traffic and hope they don't write down your rego or have a camera? 2. generally speaking is it safer to split down the middle of 2 lanes, in between the cars, or on the edge on either the right or left side. I see pros and cons for each: down the middle of the 2 lanes - good because most of the time the gap is pretty big, bad because cats eye reflector bumps to run over, cars changing lanes, tight gaps from trucks/buses/people blocking you. off the side edge - sometimes bumpy/damaged/debris/junk/rocks slippery etc. sometimes you have a nice wide edge then suddenly it ends if there is a bridge or something. Parked cars/broken down off to the side to watch out for. Or do both equally have their merits and just use whatever seems safer at the time (judgement call). I was trying to filter up the middle of traffic and came to a small truck (flat bed), saw that the driver noticed me 2 or 3 times in his mirror then had a vague feeling he might have been trying to block me a bit, figured it must have just been in my head and went along to filter, then right when I was in front of him he swerved a bit towards me and started yelling out and waving his fist out the window. I'm guessing it was either because he was frustrated by traffic, or because being in a truck he is worried for the safety of riders..? If anyone has any tips to consider it would help both me and anyone else new to splitting/filtering.
