These 25mph speed limit signs are equipped with a speed radar and a number display. Nothing strange about that, really. Until you notice that the billboard displays horrible figures—like days in hospital or crash bills—based on your speed.
I don't know how it calculates the numbers. Maybe it's just a speed display, maybe it uses some logic to come up with the accident bills costs or the chance of a crash. I do know, however, that people respond to fear more than to fines. 46 days in the hospital won't be fun at all, so grab your steering wheel with both hands, and please drive safely. [Direct Daily]
