Licence plates are so very ugly, especially when applied to the beautiful, streamlined shape of a sportscar.
Today’s invention is therefore a system to make your plates visible only when they need to be.
Normally, as you drive along, the plate would be mounted on a sunvisor-like flap on the inside of both front and rear windscreens (thus creating no unnecessary drag).
When you stop your vehicle, on private property, the plate visor would automatically sense its location and fold up against the interior roof of the vehicle, so that its gorgeous lines could be appropriately admired.
The internal plate could even be automatically illuminated, when on display, in proportion to the ambient light level, so as not to invite accusations of law-breaking.
