Probably been done a million times but it's been a while since I've seen a thread about splitting, so thought there'd be no harm in starting a new one. I just read the thread about the bike/car accident this morning and Flux's comments - esp in regards to the 30kph limit - have me thinking. Like many others here I have a lot of respect for him as a rider and value his posts on the art of riding. Flux wrote: Firstly, is this in bumper to bumper peak hr traffic on multi-lane hwys? Or are you talking about a single line of banked up traffic on a two-way rd? I've only just started splitting (only on multi-lane hwys) and I'm interested in clarification on this. I'm also interested in hearing others thoughts on splitting on multi-lane hwys. After talking with other netriders I've decided not to split if traffic is going at more than 40kph. I'm glad for that because I had an encounter with a cop car this morning whilst riding in peak hr traffic on the Monash...moving at abt 50kph. The cop decided he wanted my lane (far right) because it was moving faster than his (middle lane). He must've seen the gap behind the car in front of me...must've done a quick check of the mirrors whilst I was passing through his blind spot and without indicating moved over..causing me to move to my right to avoid a collision. He saw me at the last minute and moved back into his lane. Had I been splitting things may have been different. It made me think even more about the shite to look out for whilst riding in these traffic conditions. So anyway my questions are: When will you split? When wont you split? What should we look out for whilst splitting? What should we look out for whilst sitting in bumper to bumper traffic that is moving at a medium pace? (eg 40-60kph?) Any other thoughts on splitting are appreciated.
