So you're the one. Move to the right. The left lane is for passing not camping lost in the music.
In what country? Here in America the left lane is for drones. The middle lane is for trucks. The right lane is for getting on and off. So what we do here, get on and swerve through the trucks to drive slow in the left lane. Then swerve through the trucks again to exit. We used to have signs posted Keep Right Except To Pass but no one did that and so being nice Americans we caved to the lowest common denominator.
