Speed Camera Avoidance

One frequently sees plates that are so filthy that no camera would pick
up any image.
The most common type of device (GATSO) makes an infra-red image as well
as a photographic one. Neither dirt nor, I suspect, the reflective spray
that is the subject of this thread, will prevent an infra-red image of
the number plate being taken.
