OK, but being the devil’s advocate:
If the contravention only occurs when entering the box, and the video should be showing this (while it is not), then that may be a ground to appeal indeed – but just from a purely legal perspective.
In fact, the camera zooms out in 0:18 and shows almost the entire junction (BUT still not the place I was standing at and entering the junction from!).
Might they argue that even though the exact moment of me entering the junction is not visible on the video, it still shows that I could have clearly seen at that moment that there was no room to leave it? That Toyota C-HR before my car was standing there for quite a long time before I even appeared on the video (thus – allegedly entered the junction)…
On the other hand -could I say that I was going to take the left lane leaving the junction just after that beige Nissan Micra, but I looked in the mirror and got scared by that big van coming right behind me at high speed – so I stayed on the right lane for my safety, not blocking any traffic after all?
I am trying to see all the angles here before I charge at the wall head-on…
