Quite right, no excuses for those google cyclists.
Those cars are highly likely to have committed an offence though as it would be nigh on impossible to have parked the way they have using just the two dropped kerbs to the far left. It is an offence to drive over a footway if there is no dropped kerb where you mount the pavement. Not sure what harm they'd cause in this case but then this thread isn't about cars on pavements. Or leniency.
