Instead of Yosemite Sam and “Back Off!” you’d see Yosemite Samsonite and “Half Off.” Instead of “How’s my driving?” you’d see “What’s in your wallet?” Instead of silver silhouettes of Playboy bunnies, you’d see an ad for the return of the Volkswagen Rabbit.

Yeah, but who wants to see this? Especially since, sooner or later, every static ad will become animated and tail-end commercials could bring rear-end accidents.

For an even farther-out idea, see “The Animated Electronic Bumper Sticker Screen.”
