Was it on a motorway, "dangerous" A road, or built-up area?

IIRC it was on the A1, early hours in the morning, and only 104Mph, in a
Vectra. I've driven a vectra at an indicated 145mph, and they are a safe,
stable, capable car. Annoys the hell out of me this kind of thing.

If you want to see bureaucracy at its best see this one
