The idea local councils deliberately set out to trap drivers who break parking laws as a means of raising funds is "a myth", according to a campaign group for local authorities.
Councillor Peter Box, chair of the Local Government Association's Economy and Transport Board, said:
It is frustratingly familiar to hear Big Brother Watch again peddling the myth that councils are enforcing parking regulations just to raise money.
However, it is wholly inaccurate and misleading for them to claim councils are alone in warning about the dangers of banning the use of CCTV for parking enforcement.
Road safety campaigners, schools, disability and pedestrian charities and councils have all come together to warn the Government that banning CCTV parking enforcement will put school children and disabled pedestrians at risk and worsen road safety.
According to data released to Big Brother Watch via Freedom of Information requests, at least 36 local authorities are using static CCTV to capture traffic violations, and some 58 councils use CCTV cars.
London boroughs accounted for around 90% or £285 million of revenues raised through CCTV cameras, Big Brother Watch said. The top five highest revenue-raising councils were Camden, Ealing, Lambeth, Westminster and Harrow.
A Surveillance Camera Code of Practice, published by the Government, highlights the need to use CCTV for traffic offences "sparingly", the campaigners said.
Bristol City Council has cancelled a parking ticket issued to a driver who pulled over into a loading bay to help an injured cyclist.
Janet Young gave first aid to a cyclist in Church Road, St George, Bristol, who had clipped a pavement and fallen off his bike.
Mrs Young, a receptionist from Bristol, said she would do the same again despite having received a parking ticket.
"I think anyone would, of course we would, its just [instinctive] to help someone in need," she told the BBC.
Mrs Young's car was caught on camera by a parking enforcement vehicle, "so they would have seen the accident", she said.
The parking ticket was overturned after Mrs Young lodged an appeal with the council.
A council spkeswoman said its parking wardens "have to follow the letter of the law" when issuing penalties, but added: "Appeals are considered sympathetically in certain circumstances, providing there is evidence."
With clamps no longer an option now in England and Wales it was inevitable that the number of parking charge notices (private parking tickets) would increase, the AA has said.
However, the car insurance firm criticised the "unregulated" private parking enforcement industry, which they blamed for the frequent use of penalties.
We are pleased that after decades of clamper extortion their practices have largely been consigned to history.
However, private parking enforcement remains unregulated and is a free-for-all when even firms signed up to a code of practice breach their own rules. It seems many of the notorious clampers have moved their sharp practices to private parking enforcement.
According to the AA parking penalties are becoming a problem and these two cases highlight why:
A diabetic who slept slightly beyond the two-hour limit at a deserted motorway service area in the early hours after having concerns about his blood sugar level.
Despite obtaining a doctor's certificate, his appeal was rejected by the parking firm, which also said he could pay the £60 by monthly instalments although he said this would cause hardship.
Another AA member in London was threatened with a £160 parking ticket which breached the £100 maximum recommended by the British Parking Association's code, to which the enforcement firm was signed up.
Banning wheel clampers has not made parking an less dear on drivers as they are now subject to automated "penalty" tickets when they break the rules in a car park, the AA has said.
Last year wheel clamping was banned from operating in private car parks but 12 months on parking enforcement firms are still issuing tickets.
The AA said private parking operators now rely heavily on CCTV and automatic number plate recognition (ANPR) to watch drivers and issue tickets through the post when they put a foot wrong in parking areas.
Complaints against private firms posting penalties which arrived a few days after the alleged offence were coming thick and fast, the car insurer said.
Edinburgh and the south coast of England were the worst offenders.
