Reclaim the fastlane
Finally, a grassroots effort I can wholeheartedly support: Left Lane Drivers of America.
The organization has a website dedicated to reminding slow drivers
to get out of the left lane. It's main purpose sems to be selling these big decals, which, as much as I hate slow drivers in the fast lane, I would never plaster to my own windshield.
It's a noble cause, but I doubt that the group's going to get people to stick those big stickers on their windshield in a city where people are even loathe to put free parking stickers on their waxed babies. Good luck to them.
