>Or they'll just change the standard and charge more people.
This is a Congestion Charging scheme dressed up as a Clean Air initiative. The original Congestion Charge proposals were a bit draconian -- Manchester is a bit more compact than London and hasn't got the extensive network of train and tube services so from what I saw most Mancs would have to pony up just to leave the house -- so I daresay they were shelved as potential political suicide. Introducing them as a "Clean Air" initiative with the vague promise that maybe they'll be withdrawn at some future date.....come on, does anyone seriously believe this stuff?
