The video shows a clear contravention; were you not aware of the meaning of the "Flying Motorbike" signs ? There has been a similar case on here, with the same layout, but a different location, I think. I'm not sure how it turned out. This is a very recent change as GSV of August 2025 doesn't show it.
There may be a 'technical' appeal based on WF mismanagement of the enforcement process, so don't pay-up immediately, and wait to see what may be suggested. Appeals have been won on payment and appeal webpage errors. DOwnside is such appeals are normally only dealt with at London Tribunals with the full PCN penalty in play, but that is all, there are no other costs, and if you win, nothing to pay.
