Ever wondered why the police tell you to get out of the car, when they pull you over?
They never used to do that. They used to speak to you through the drivers window.
I think I've figured out the reason for the change.
They don't want the encounter recorded on your Dashcam.
Then take your other recording device with you.

The last stop I had was on a motorway back in 2017 for 'No insurance' in the early hours, - while driving a two month old company car - the company insures its own vehicles so didn't put it on 'MID', but I was unable to confirm Insurance because of the time, they checked the car was registered to large company, my works ID and DL proved who I was.
But plod didn't understand this, his view was it's not in the computer and I have targets, so instead of being given a 'HORT1 notice to produce' I was asked to sit in the back of their car for for about thirty minutes on a busy M62 near Leeds, I started to think they thought they had cocked up.
I was threaten with the car being seized, me being arrested, etc. - 'I don't give a toss about the car - it's not my car officer, it's insured' finally they gave me a HORT1 producer, they then left me to drive off.
I then took the works emailed PDF to a Police Station later that day, No, they wanted 'PAPER' copies of the insurance certificate, I went to the print them out took them back, the Desk plod wanted the 'Originals' to look at, I explained that there was zero chance of that happening because it was an trade 'Open certificate', he left to go to speak to some more 'senior' came back, OK, I can go......

So, a big thank you to the West Yorkshire Police for proving some real jobsworths exist in the Police.
