Split, Yes I would agree, but lets face it, it is a pretty natural reaction, I would suggest, by everyone (almost) who comes across an 'unknown' speed camera. The same goes for when you see a police car on the side of a road. A great many people just hit the brakes.
Even as mlc admits above, speed cameras are there to generate revenue and we should therefore, question the erection and use of such a device that 'contibutes' as a 'hazard' to road users. The number of skid marks at speed camera locations bears out what I mean.
