No fingers crossed at all. It's the law.
Now, whether Worthing are now up to speed on the law I don't know. My only interactions were 2-3 years ago for my daughter-in-law. We won both and got costs awarded against them for the second.
At that time their obdurance was matched by their ignorance.
Let's see how they treat you.
If they play silly b*****s then, as I make frequent trips to Worthing and I'm retired with time on my hands(at least outside school holidays), I might just observe the conflicting situation within that zone(which might be repeated elsewhere for all we know) and write to them. But not until your* PCN has been determined.
*- on this point, are you the registered keeper with current DVLA details.
