The numbers are in on speed cameras, this is an “investment” vehicle for the government costing tens of thousands that has the abiltiy to pay for itself in a matter of hours. Clearly from the images we see here the people have spoken and speed cameras are not going to win you any votes. Slowing down in camera zones and speeding up again has become a national sport! They don’t save lives the numbers have proven it, policing motorists was much more effective when it was not a business with budgets to meet. In certain parts of the world when the cameras rolled in and the people slowed down speed cameras did not meet the budgets - it was then certain governments reduced the tolerences in order to get the numbers back up.  This is not a practice that lines up well with the intended effect of reducing speed on the roads. If they were serious about getting the accident rates down then they would focus more on road fundinig and driver education. But wait that might actaully cost money.
