Stim: I definitely remember her telling the one about the woman having trouble in traffic -- a recently only just passed-test driver. A passing police car turned on its PA and politely and helpfully asked the traffic to stop for a moment, please, while the lady manoeuvred her car out of the tailback it had got caught in after taking a wrong turn. She tried a three-point turn as instructed but didn't brake in time and backed into one of the other cars. Forgetting he had not switched off, the policeman exclaimed, heard fortissimo by every driver and passer-by around, "What the fuck is the stupid bitch doing now!" [of course Aunty Peggy said "What the hell", but...].

Now, that is certainly an urban myth which I have heard elsewhere, tho I am not sure if Snopes includes it. Peggy, however, retailed it as her own experience -- not even claiming a foaf in this particular instance; said that she was there, she heard it, it was near that awkward junction just down Hampstead High Street from Hampstead Station, "just as I was driving by the other day". She lived near Belsize Park Station, which is about ¾ mile further down that road, after it has become Rosslyn Hill, just to furnish the sort of exact detail with which she would augment her Urban Myths.

So as she was wont to retail such tales as foaftales, or even her own experiences, I still wonder, despite Uncle Dave's prescriptive animadversions that I still don't quite see the point of, whether the OP story is an UM, even tho I can't find any other examples; or if 'Leicester Square' really did happen to some foafs of Auntie Peggy's.
