This is the video Ealing council sent me, traffic was flowing in both lanes without issue I had a Large sprinter van in front of me rather than a car blocking my visibility of traffic ahead on it. I entered while the van in front was still moving and then suddenly stopped causing me to stop in the yellow box, furthermore the car in the second lane also stopped without moving forward even though he/she had 1 car space clear stopping me from going behind him/her to clear the yellow box. Please let me know if I have grounds of appeal in your experience. Link to video not allowed please message m for it. Is it true that 'A yellow box junction must be at the junction of at least two roads' ?
