To stop reckless drivers in the Ukraine, a special device was built that would release a "human shaped balloon" at a pedestrian crossing, so the driver would have no choice but to show down. (in quite a panicked reaction, I might add).
Scary. I know I would freak the hell out of I saw this on a dark road. The device is also pretty clever in how it'll only release a ghost if the driver is speeding quite a bit, not when the drivers are sticking to the limit. I wonder if any of these ghosts caused an accident due to swerving-to-avoid-collision reactions?
Either way, impressive.
