Are we watching the same video? This one with the Waitrose truck?

That's a regular all-traffic carriageway lane they're in. There's no way it's 1.5m wide. It's probably closer to the 2.2m minimum than the 3.7m recommended, but even 2.2m is OK for cycling two abreast, isn't it? Fark, 2.5m is considered OK for two cyclists to pass each other in opposite direction at full chat IIRC.
If you'd like more confirmation that it's not 1.5m wide, at 14 seconds in, you can see the famous old tube trains of The Village Underground in the top-left of shot. That means they're about here on Great Eastern Street, heading north: https://www.google.com/maps/@51.523...4!1s1IAnhRa7gFj1Ju2kvdW89w!2e0!7i16384!8i8192
The only time when I spotted the inside riders on the outermost double red line is when Waitrose driver passes them, causing the outside riders to move in slightly, which in turn causes the inside riders to move in. Within acceptable safety margins IMO, especially as all but one rider seem to be on steady and sturdy hybrid/MTB/city bikes, not twitchy HDAU road bikes (remember the famous collision between a city bike and a road bike in Blackfriars Underpass: city bike wobbled a bit, road bike cartwheeled).
I agree with you about the futility of being legally correct if there's a collision, but I completely disagree that the riders are creating significant danger for themselves. They are using the road normally, legally and, as far as I can tell, in accordance with current advice in the Highway Code and the National Standard for Cycle Training. The danger is created by the close pass and I feel that your views on positioning may be mistaken due to misestimating the lane width.
If you spin around in that Google maps link you see the same building on the right as in the video, the curved end one. That's also a vauxhall vivaro van of the same model as I have. It is well within the lane markings where the cyclists in the video were riding. Since that van is 1.94m or 2.205m with mirrors included you can estimate that the lane in question is at least 2,2m wide probably a bit wider. Certainly not a 1.5m wide lane but likely 2.5m wide I reckon. Plenty wide enough for 2 abreast.
