Cabbing is a very hazardous occupation, not really knowing at any given moment what’s going on with that stranger in your back seat behind your unprotected back. “See-nothing, know-nothing” is just basic self-preservation where TV-cameras are concerned - let it come from the boss back at the office, right? I’d cut them some slack.
Danny DiVito wouldn’t make it past the second day of training in a real-world cabstand - he’d freak and run screaming from the building! :P :)
