I have never ridden a bike but I have always pulled into the left to allow bikes to pass. In a traffic jam most of us tend to look for bikers on the right, why should I pull to the right in on-coming traffic if I'm in outside lane. When they ride between the 2 lanes, I think that it is their responsibility to make sure cars are not moving back into the left lane. Using a bit of road sense we should accept that the guy in the left lane would be the one to look for bikes while the biker watch for cars coming from outside lane. My reasoning is that its too easy for the guys in outside lane to re-act to oncoming traffic and have to move in closer to cars in left lane, especially if an emergency vehicle is coming the other way.
All this then makes one wonder why bikers are allowed to ride between cars? And why do we accept that a ****** off road user can take out frustration on your car. Does that mean if we had handguns the motorist can then step out and use biker as target practice? We need to curb our anger and frustration on the streets because you never know if the guy next to you has just had the worst day in his life.
