Signs, signs, everywhere there's signs

On the way in to work this morning, JoDee and I noticed a test message on one of the new roadside signs on I-275. These signs really haven't lived up to their potential, though. Most of the time they have pithy sayings like "DON'T DRINK AND DRIVE", or "WHEN SNOW FALLS, SO SHOULD YOUR SPEED", or "OBEY!" (OK, so I made up the last one... I think). On rare occasions they'll put up an Amber Alert or an Accident report ("ACCIDENT AT 9 MILE") but those aren't very helpful. I think they shold have something like "SILVER PORSCHE DRIVING LIKE IDIOT", or "GREEN EXPLORER, STOP TAILGATING", or "BUICKS MUST DRIVE ON SHOULDER". Of course, my subversive mind came up with the following that I'd love to put on there at some point: "SLOW DOWN, DICKHEAD". I wonder if that would get people's attention.
