Who cares if they pay the charge or not? What I want to know is whether they'll pay the *fine*!
£5.5 million in charges is 687,500 incursions at £8 a pop (I know its more now, but I figure they've been at this for a while).
TFL would tell you or I that "any vehicle recorded as having been in the zone during charging hours but where no daily charge has been paid by midnight the following charging day must pay a penalty charge."
I reckon 24 hour reduction is up for most of the 687k too, so its the full £120 they owe...
(Runs off to do the math....)
£82,500,000
