77mph through mobile speed camera in a 70mph zone (dual carrageway). Whats the likely outcome? I know all cars speedo's are often over compensated on speed, does anyone know what by how much the scooby speedo is above your *TRUE* speed?

normally 10% + 2 mph so 79mph in a 70mph area but that may just be folk law.

As far as each car and speedo is concerned it an individual car thing and by law the speedo must not under read and not more than 10%over read
