Change Lanes, Avoid Speeding Ticket

I'm guessing this has already made the rounds back home, but just in case, if you change lanes halfway through the process of being photographed, the camera screws up and can't dish out a ticket. I'm guessing that this will soon put a stop to the "for road safety" reasoning behind the cameras, as everyone suddenly starts randomly changing lanes when they come up to these on the Motorway. So, will the government fess up to the fact it's just to get more money, or just ignore the whole thing?
