There didn't look to be any cameras on the M.23, but there may have been.
However there will have been on the roads to or from, unless the driver planned the journey really well.

The mileage on the speedo is almost visible, the image would probably clean up.,, 1st unique distinguishing feature.
There's a part image of the drivers left hand,,, 2nd unique distinguishing feature.

It's possible that at least one of the vehicles, at least 5, they passed would have had dash cams especially the lorry, 34secs.
The lorry will be easy to find, there aren't many companies who produce large precast concrete sections.
The graphics on the extended body van at 41 secs would be reasonably easy to identify.
It won't need much more, once found for a successful procecution.
