Please report dangerous drivers to the police - Roadsafe. Report to plod, not just whinge here.

But they'll use the right lane, as they usually seem to anyway, I don't think riding a few inches to the right of primary will put someone off doing this. Maybe if you swerve from left to right across both lanes.

It's enough to make it more of an inconvenience for them to overtake you to the point that they might as well just wait behind you, it mean they'll have to do a very big manoverve to get to the bus lane as oppose to riding in primary or near where they didn't have to do such big manoverve.
