The European Union has passed a measure requiring cars to be fitted with a nagging speed nanny systems by 2022 (archived). The naggers will import speed data from the vehicle's GPS reported location as well as from a forward pointed camera intended to read speed limit signs. During the first implementation phase driver's will be able to over ride the system and disable it, though every time the vehicle starts the nagger will be enabled by default. Eventually EU social engineers have expressed their hope that with continued exposure to the nagger, they will be able to remove the allowance for its disabling. Mandatory pre-wiring with a harness to allow installation of alcohol interlock devices without further vehicle modification is included in this nanny state measure as well.
Post Brexit Britain will also suffer imposition of the naggers as well under its current transportation regime thanks to the eagerness of bureaucrats to agree to absolutely anything at all, so long as they have an opportunity to agree to something.
