I have heard a few people talk about some of their rules of engagement when lane splitting. Here are mine all in one place:
1) Traffic must not be travelling over 15-20 mph when I begin splitting
2) I never exceed the traffic's speed by more than 10-15
3) I watch cagers very closely and have become very good and anticipating their moves based on body language
4) I hang back if I know the driver has no clue that I am there. I wait for them to see me (FJR brights on) and if they do not, I honk before proceeding...this is only when traffic is moving...I don't do this if traffic is stationary.
5) Bike lanes are for bikes and medians are for debris, cops, ambulances, and the idiot cagers who pull left to see how lon the traffic jam is
6) some cagers take offense to your ability to go faster than them and will try to squeeze you, or make the space too small. Be patient, wait for the car next to them to make room for you one way or another and wave thanks to the nice guy.
7) Stopped traffic...watch out for vehicle turning left through stopped traffic. 10-15 mph rule allows for quick stops. I have been surprised by them and pedestrians walking through stopped traffic...go slow and be careful especially on surface streets.
8) Look for bikes behind you that are more aggressive...pull over for them and let them by. They tend to open space for you, and being crowded is the last thing you want.
Why are Honda CBRs always carrying the jerks that tend to crowd? Not all CBR riders do it, but I have seen at least 5 CBR riders crowd me, not thank me for getting out of their way and various other rude things...BASTARDS
