Last week, I got my hands on some Freedom of Information (FOI) data from the Metropolitan Police on the numbers of speed tickets generated by cameras across London. It was a bit of an eye-opener, so I decided to map the top 20 most profitable cameras in London.

The temptation is with this kind of information, is to dismiss all motorists as evil law-breakers etc etc etc, but what I wanted to do was try and paint some colour around why a particular camera makes more money than another one.

London’s most profitable speed camera is in the Limehouse Link westbound. Find out why here.

Both ITV News and the BBC picked up on this story.
