I love getting stuck behind a moving roadblock. I will flash my headlights as a notice to let them know faster traffic coming up. That will usually get them to move over. But there is always that ass that will not move over until it is his exit and then he will cut from the left lane across the right to the ramp. You usually see those drivers with big hats and wrap around sunglasses on. Don't forget the turn signal that has been on for the last twenty miles!
