I'll throw another one in the pot then...
...was it you on the M1 southbound (South Yorkshire) last night (Sunday) at 9:15pm in a Silver 320d, registration starting BF62?
Very nice car, I noted the pro nav system. I assume that was what you were playing with as you had your indicator left on for about 2 miles and veering around your lane quite a bit
I assume you were busy playing with all the toys onboard - so forgiven in my mind. Enjoy.
