I feel like you people can't read. I said they ride on the line or sometimes use the sidewalk (when there is a bike lane going in exactly the same direction), not that they don't use the lane at all. The point is they ride on the line between the car line and the bike lane. It's especially problematic when there's only one lane for the car and the cyclist is swerving in and out of the car lane.
I wouldn't use a highway in general anyway since, as I said, I don't drive.
