As much as i love bikes.....it's that type of attitude that sees alot of bikers on their ass after being hit by cars! As a couple have said, steady paced filtering so you don't have to sit in traffic is fine, but ultimately you are overtaking people which is always a risk when you're not using a seperate lane as such! Why on earth they think it's fine to filter at 60mph i don't know, it's so easy for them to sneak up on you without being seen. The thing that really pisses me off is when bikers overtake traffic when you're coming towards them, using your side of the road trying to force you off the road.....ultimately you're highly likely to come off worse when you come off your bike so why some people seem to wanna raise the stakes of it happening i don't know
