Strangers checking other cars details

[milu]

Got a lift to the station yesterday morning with some friends. Pull up at the lights and a young chap in a car to the side gestures for my pal to open the window.
He informs him that the MOT ran out a few days back!
Apparently according to the wife who was driving,he'd been behind a while.

So various points on this.
The wife was happy since she'd been assured by hubby that the mot hadn't expired yet. Cue domestic!
Hubby opposite of course because he's now in bother.
He is also a bit miffed that a guy is driving behind,running their car details just for the sake of it. I said some others might be less than friendly after being told the news. Of course he's doing it whilst driving too.

All seems a bit weird even if it has actually done them a favour.
Is this a thing now then? Sort of a follow on from dash cam nosey parkers.

I was thinking the young man might get into bother if he does it to a lively character
Defo not an off duty cop
A bit sad I thought

As stated in the OP the wife was happy enough with the reminder.
Nothing suspicious going on other than a car full of suckers up early on a Sunday to go to Christmas markets

Whatever the final analysis it still seems to me that folk are able to get involved in others business very easily these days.
