I know there are many drivers that feel as long as they are going the speed limit then it doesn't matter how many cars are stacked up behind, but is this really the best we can do? I have an idea for a campaign from a safety and courtesy point of view rather than regulatory we might find more of the slower drivers simply pulling aside to keep the flow moving. I call it the "Look in your mirror" campaign.
 
I can see a TV PSA with a motorhome leading a long line of frustrated drivers - that's the problem. Then a shot of the motorhome driver seeing the "Pull-over" sign and pulling off into a pull-out with happy drivers smiling and waving as they drive by(?). Also, I can see an addition to the white "Pull-over" signs with an additional part of the sign in color with the same "Look in the mirror" phrase; this extra part would be similar to the orange, "double-fine" part of the speed limit signs in the Highway Safety Corridors.
