Some snippets of info for you:
Amount raised in fines by cameras in 2005-2006: £115 million (£114.6)
Cost of running scheme: £100 million (£99.5)
Surplus from cameras: £15 million (£15.1)
Estimated number of cameras in the UK: Six thousand (6 000)
So, we have an annual profit of over £15 000 000 all in the name of "safety". Just exactly how is this money spent on enhancing the safety of motorists on the public roads?
Oh yes, on more cameras...
