Many many yonks ago, I would "commute" at weekends from Portsmouth to Lancashire. Mrs Mick F wasn't a Mrs then, just a Miss.
250miles each way in a Mini Van.
I would leave on a Sunday evening about 9pm and drive M6/M5 and across along the A roads ........... well before bypasses and dual carriageways. I would drive through the towns, and one night - in the wee small hours of Monday, I was passing through Cirencester. In those days, there were hardly any street lights.
As I turned right onto the road out, I saw a couple of people walking facing in my direction. One of them had a torch and it bobbed up and down as they walked.
I passed by, and as I did, I realised they were coppers and I saw them in my rear view mirror turning round and shining their torch directly at me.
I stopped. The coppers ran up to me and told me off for not stopping!
"Didn't you see me flashing my torch for you to stop?"
"I saw your torch well enough, but it's dark, you're wearing dark clothes, and all I saw was two men walking with a torch. I had no idea you were policemen or even wanted me to pull over."
They had no answer to that!
I was 19years old, and a cheeky confident sod.
Any road up, they checked me out, looked over my car, checked the tax disc, checked my tyres ........ and wanted to know why the tyres were very warm. I explained I'd just come down from Lancashire down the motorways having done over 100miles non-stop.
They made some notes, and then allowed me to go.
