It there was a device on sale that you could take into a department store that would tell you where the security cameras were and the position of all the store detectives, people would say it was wrong but isnt that what Sat Navs do in a way? Why do we have signs saying that there are speed cameras in the area? why not change them to show what speed you should be driving if you speed you deserve to get caught. By the way I dont drive could explain my stance but isnt breaking the law breaking the law??
Some stores do warn that they have security, and cameras are visible.
If a sat nav warning causes us to slow down , that's fine, although I would agree it may tempt some to speed where they see no speed cameras are used
Because one hopes, idealistically, that speed cameras are there to ensure drivers keep to the limit for safety reasons rather than for catching drivers unaware to collect fines.
