Device: An orbital high energy short pulse length super-radiant projector
Purpose: For those motorists who pull up past the “stop line” at STOP signed intersections.
Effect: The projector trims the vehicle back to the “stop line” so the motorist is no longer breaking the law.
Side effects: Of course the motorist will now have violated the littering ordinances since he/she will have put junk on a public thoroughfare. And the situation could get a bit messy if they have pulled up so that the passenger compartment of the vehicle is over the line?
