Stop me b4 I do it again
By whom? I can believe it was too expensive in the past but I don't imagine that the main tech is all that different from what is now being used to monitor the gates (which three months on they still have not fitted in St Matthews Road). But I don't know.
I suspect any resistance from the council on the grounds of cost will not be because of the cost of tech, but because of the cost of staff time in handling endless requests for exemptions, resolving mistakes made by the tech, and general administration of the system. I doubt it's straightforward. Remember that it costs £60m a year to run the congestion charge. That's recoverable but only because the aim is to charge drivers that enter the CC zone. Lambeth is trying to stop cars going though filters so if the LTN works, it won't generate any revenue, but will still cost lots to administer.
