Forget roadside checks and coin-tests! Treadcam, the latest technology means that the police can examine your tyres automatically without even stopping you! This article in a recent Metro shows how the system works. An electronic reader, similar to a fingerprint lens, is placed across the road and as a car drives over it the reader scans the car’s tyres which a roadside camera snaps its number-plate. If the tyres are badly-fitted, punctured, overfilled or bald the computer in the reader automatically alerts the nearest patrol car and the car is intercepted. Here’s the online version of the article: http://www.metro.co.uk/news/877090-treadcam-sensor-snares-drivers-that-have-tyres-below-legal-limit
This is just one more example of something “convenient” and “sensible” being used as the thin end of a wedge whose other end is total Big Brother surveillance.
