10 rules to driving a black cab

I normally have a pretty good experience with Black Cabs, not all, but most. *

I gave way to a black cab swerving over 2 lanes to get to a fare. I got a cheerful thanks and wave which I returned. They're all just trying to make a living.

*but some mini cabs on the other hand.....

if you're following / filtering a cab keep an eye on whether they've got a fare. if not they're gonna do something unpredictable
