Congestion Zone in London - The FOI request that exposes the handy racket business

There are big signs with big red 'C' letters to let you know you are driving into the zone.
However visible sometimes when we drive our attention is taken away on our driving and we miss a big sign. This happens a lot when driving in big cities and even more to those who come rarely to such big city.
A number of people who are unsure whether they went inside the zone decide to pay the charge rather than face a fine. In other words some people pay the charge although they didn't drive in the zone.
There is no system in place for TFL (transport for london) to be able to tell whether a car has been driven inside the zone or not; except when issuing the fine.

The FOI request is a compelling read on the subject.
