Another motoring one.
Unlit dual carriageway, good visibility, little traffic.
So you settle at 80mph 😳
But what’s this? Someone catching you? Is it 5-oh?
Slow to 70 then.
They catch you… And sit behind you.
And you can’t shake them off. Slow gently to 40, still there, accelerate briskly, still there. Seeing it’s not 5-oh, up to a quick , 90… still there.
The only way to shake them off is turn off or stop on a layby.
WHY????
