A new bus lane camera said to be bamboozling drivers is raking in £20,000 a day as a result – making it Britain's most lucrative.
The amount of cash it has made means it leapfrogs a temporary camera placed on the M6 near Carlisle, which in two months during 2010 generated half a million pounds.
The camera, in Hemel Hempstead, Herts, has made £600,000 since being installed one month ago.
More than 10,000 have been stung by fines, though the road is so poorly marked that drivers say they're being confused into driving where they shouldn't.
It's a viewpoint that local MP Mike Penning agrees with – so he wrote to Hertfordshire council to ask that the camera be switched off.
"No," came the reply, with council transport boss Stuart Pile saying it has "no plans to suspend enforcement...or refund motorists who have been fined for illegally using the bus lane."
