Uk drivers, if no one can trace anyone else by their car plate details, why do reality tv programmes like Police Interceptors blur the plate details

Because if the stopped driver is suspected of doing something illegal it's possible that same vehicle is suspected of being used in other crimes.

Villains watch tv too !

So the fewer details you make public the better

A lot of the time it's because the car has been stolen and they're hiding any part of the identity of the true owner of the car
