<Snip> Also, it's useful for tabloids to conflate "all money raised for motoring charges, including fines for improper use of bus lanes/ parking illegally/ offences that require your vehicle to be towed away" with "parking charges" - a disproportionate amount of the money will relate to a smaller number of major offences (which may cost the council some money due to the need to pursue people through the courts etc) but that gives the impression that Councils Are Raking In Millions Of Pounds From Car Parks And You Are Footing The Bill (and similar outrage headlines) << I wish we could separate "car park revenue" and "fees/charges for illegal parking or improper driving"

The figures quoted in the media are usually the combination of all charges and penalties for both on and off-street parking, and may include income from moving traffic contraventions including bus lane enforcement.
Income from parking charges should be viewed as a separate issue from enforcement penalties. However, in terms of public perception and the potential impact on town centre vitality the two may be linked where an authority takes an overly keen approach to enforcement. For the law-abiding majority it may make a town centre seem an unattractive place to shop if you regularly return to your vehicle and find an enforcement officer standing there waiting....
However, in decriminalised parking/traffic enforcement there are no 'major offences', just a refusal or unwillingness to pay at the earliest stage possible. The cost to the contravenor increases as the enforcement process progresses, but so do the costs to the authority, and the net income per-PCN typically reduces as progression occurs. Well-run parking operations usually generate the vast bulk of their income/surplus via PCN's paid within the first 14/28 days.
The main issue is the lack of clarity on how the money is spent. Section 55 of the Road Traffic Regulation Act 1984 details the requirement to account for 'parking' income and expenditure, and limits the things that any surplus can be spent on. Most people wouldn't object to parking revenue being spent on improving and maintaining car parks, improving and maintaining roads (including cycling and pedestrian facilities), contributing to public transport provision, environmental improvements etc.
The problem comes when authorities bleat they don't have enough money for certain transport projects, but via clever accounting money from the parking account is being transferred into general fund expenditure. E.g. In London no authority should be claiming a lack of funding to repair potholes if they are able to transfer parking money into their general fund.
The other issue is that the purpose of on-street parking management and enforcement should be to manage the use of roadspace for the benefit of the community as a whole, not as a measure to raise revenue on its own. At least one authority has had its knuckles rapped for increasing parking charges for the purpose of making up a shortfall in the
surplus it was expecting to generate from parking. That kind of behaviour is what gives the system a bad name, and outrages the headline writers.
