Considerably more Brixton.
[edit - I've googled]Over 50% of appeals are successful.
Where do you get that from? Parking enforcement and appeals statistics | London Councils
London's boroughs have carried out parking enforcement since 1993/94 to ensure that the capital's already busy roads are not further congested with unnecessary hazards and are safe for everybody that uses them.
Penalty charge notices are issued to people parking illegally, wrongly using bus lanes, committing moving traffic offences like stopping in yellow box junctions, or for contraventions under the London Lorry Control Scheme. Less than one per cent of these penalties are appealed through the independent Parking and Traffic Appeals Service (PATAS) known as London Tribunals since 2015.
[edit again - ok - less than 1% are appealed, but half of those that are appealed are successful. that makes sense]
I think I've had a grand total of 3 motoring fines in my life. Once on the yellow box outside the fire station on West Hill in Wandsworth (supposedly the highest revenue yellow box cam in the UK - someone cut front of me from the lane to the right and blocked my exit.), one was a parking fine in Covent Garden and I was bang to rights.
Last was when I was helping someone move on a street in Brixton (legally loading but from a third floor flat so car doors were shut and locked) and they didn't put the ticket on the car - successfully appealed that one but took multiple letters and I had to go in person to an appeals hearing near Trafalgar Square - it took so much time it really wasn't worth it.
I avoid driving, especially in London, but it's really not hard to avoid fines.
