I see it as a way of advertising, "Eat at Joe's", or some other type of offensive message on some other person's car. Not going to be a big hit, I'm afraid. . .

The allowable msgs would be preprogrammed to pertain to driving. How's that?

I'd rewire mine to display sexually offensive, yet grammatically correct phrases involving the mother(s) of the driver behind me.

How about we make it hard to get a license instead? You know, require a demonstration of both driving ability and traffic theory?

Instead of, you know, tests wholly comprised of stopping at a stop sign and parallel parking? Not a sermon, just a thought.

An electronic sign on the back of your car, while distracting, should prove a popular advertising medium. Think of it: You hit the brakes and the sign says; STOP AT JOE'S FOR THE BEST PRICE ON XXX! You could declare the car as a business expense and rake in fees for displaying the ads. Why not?

Totally! You could get one of those outdoor plasma monitors, and wire it all up! Think of the possibilities. Wide-format movie trailers! You could even mount speakers so the people could hear the dude who does the voices for every trailer ever.

"In the future... A world controlled.. By technology... A boy... A girl..."

When I was in Las Vegas last September I noticed a few flatbed trucks with about 8' X 12' screens on the back driving around the Strip. Somehow, in a backdrop of excessive light and moving images, these just seemed natural.

I just keep a paint pellet gun in the car. Green is for hesitating when the light changes to green.

Stay on your toes.

There have been serious proposals to issue pink license plates to convicted DUI and DWI drivers; I suggest other colors for drivers convicted of other traffic offenses: red for chronic red-light-runners, yellow for lane-changers who don't signal, blue for drivers with a lead foot, etc.This wouldn't be necessary if the courts would simply put drunk drivers in jail for a year.
