For a comparison, the other week I drove 4000km across Europe and most of the speed cameras I came across were in areas where the speed actually makes a difference i.e. in towns and residential areas. Along a three lane motorway it doesn’t make much difference whether you go at 130kmh or 160kmh, if you aren’t paying attention and do something stupid it’s going to end badly either way. From seeing where speed was actually enforced, it seems that the authorities here believe that too.
