Don't see what happened there. The van merged between the two lorries. No problem?
To clarify, I should have said read the video description. The van driver was waving his fist in anger at the lorry driver which is not visible on the camera. He was not happy at all and the lorry does move back just a little into the overtaking lane so I guess he spotted him at the last minute.
It didn't bother me at all but I thought the van man's anger was amusing so I thought I would post the video.
