Ah but you are forgetting Clause 239 part 3(b) subsection 4 which says any successful appeal cannot claim compensation for loss or damage or expenses incurred in appealing. Notwithstanding your choices of action which multiply tenfold if you are claiming Human Rights, in which case you can appeal under Section 282 of the not-yet-passed-through-the-House-of-Lords Bill for Appealing Against Unfair Camera Violations Act. To be heard some time in the next Parliament, unless there is a different party in power at that time.
Vote Monster Raving Looney Party. You know it makes sense. Or at least, more sense than any of the current incumbents.
This happened to me last year. I found myself wanting to cross the Woolwich Ferry and encountered "Ferry Closed. Diversion - thatway". I didn't follow the diversion because it took me into one of the many zones-of-doom. It took me many hours of driving around avoiding any zones to get to the Other Side. Result: much consumption of the world's limited oil reserves and emissions of I-know-not pollutants which would have not occurred if I was allowed to drive in a non-LEZ / ULEZ line to where I wanted to go.
