When and where you use your 007s to play 007 is up to you, but, yes, the motorized license plate masks hide your vehicle's digits at the press of a button and, no, it's probably not a good idea to activate them every time you see a cop car or accidentally side swipe that Prius pulling your F150 out of a compact parking spot.
The retractable license plate gadgets come in Curtain Cover and Flip Down plate-hiding styles, with options for masking one or both plates, and an interior button and/or remote keychain control. This is a Curtain Cover GIF, and here's a Flip Down. Seller TryDeal notes most of its clients are: private detectives who don't want to get pegged; TV and movie producers who want to save a buck on editing out license plates later; and dudes with highly modded cars and bikes.
The covers come in handy at car meets, shows, and photoshoots filled with a lot of people and vehicles with a lot of money in aftermarket parts to their name. Apparently, enough modified cars and motorcycles are stolen right out of driveways and garages due to license plate registration with a home address that owners need this Bond toy for more than just the shits and grins that come with owning a Bond toy.
Curtain and Flip Down plate covers each have a central "brain" unit that installs inside the vehicle and has buttons that operate them. If you opt for the keychain remote as well, it will activate Hide Plate mode from up to 150' away. In both cases, an LED light turns on whenever plates are in the hide position so drivers don't forget and leave them that way by accident.
