"Graham Harrison" gurgled
happily, sounding much like they were saying:

I saw a Mercedes (Vito?) based black cab today. I've seen a couple
previously but a thought occurred today. I have this recollection
that, at some point in the past, one of the requirements for a black cab
was a minimum turning circle and that was a part of the reason why we
had unique vehicles. Was I dreaming and have they changed the
requirement?

No, you weren't dreaming. No, they haven't changed the requirements.

The Merc Vito "black cabs" have rear-wheel steering to enable them to
meet that particular requirement.

The video's worth watching...

Don't you have to be able to get in with your top hat on as well?
