Unless you, or anyone else posting on here, including me, was there, then, none of us know anymore than we have seen in the video. Personally, I would have not been happy with that HGV being that close to me (either cycling or walking). The driver may have THOUGHT he/she was showing caution, IMHO, he/she was not. That does not men I wish to see him/her sacked, hung-drawn-and-quartered, or, whatever, but, to me, it is unacceptable behaviour when in charge of a motor vehicle, particularly an HGV. I agree the behaviour of the cyclists is questionable, but, that is not the point.
