Surprised not a single road camera captured him between the two ends of the country they could then work out an average speed.
Then again maybe they don't keep recordings for that long.
Was going to say just that, all the police had to do was trawl the ANPR data, and spot his car at the start and the end, or even between any two points between.
Once they knew what plates to look for (even fake ones would not protect you) it should be simples to extrapolate distance over time measurements to get average speed.
Just general CCTV traffic cams on the motorways to spot congestion, should have been good enough images to be able to do that.
They probably did. But it didnt stick.
I don't see why it wouldn't have been compelling evidence if they did that or why it wouldn't be admissible. I suppose that getting pings at any two points would prove speeding, but that's not what he was charged with, it was dangerous driving and that's a high bar to meet. Speeding by itself usually isn't enough to prove that offence.
They would need to have evidence of the exact route he took. Without that he could easily claim he drove a different route/distance between the points to alter the average speed to suit.Was going to say just that, all the police had to do was trawl the ANPR data, and spot his car at the start and the end, or even between any two points between.

It is just a bit labour intensive and time consuming though, but it's work that is done on almost a daily basis tracking drug shipments and distributors.
