Undertaking / filtering on left?

When i am on my motorbike way too many cyclists pull out into the middle of the road without looking. I have seen 2 nasty crashes whne this has happend.
Other cyclists riding like fuckwits with no road awareness cause me more grief than cars, hgv's, motorbikes and peds combined

I think it depends where you ride. Coming in from Ealing I get more trouble from cars (like the fuckhead who pulled out from the other side of the road straight into me this morning less than 4min into my ride) and then peds. Cyclists cause me less grief but are still often doing silly stuff. Motorcycles aren't perfect but are probably the least problematic road user. I still say slow the fuck down when you're in the bus lane though. The number of times I've been saved by a headcheck as some fucktard barrels along at 60mph because it's a 'clear run' for him.. I need to move around other cyclists and potholes mr moto gp.
