Logistics (How do they film it?)
OK, there are lots of mini-cams in the car, but there are a lot of unanswered logistical questions:
(A) At the end of the ride, how do they get the camera shot of the contestants leaving the cab? Is there another crew following behind? Is there someone we don't see in the right-hand seat?
(B) Where does the driver get the questions? Does he memorize an entire show? Does he have a crib sheet? Does he have hidden communications with someone who is judging the questions/answers?
(C) How do they meet revenue requirements for reporting? I've yet to see a contestant asked for their taxpayer ID. How would they handle a tourist from Spain who doesn't have a US taxpayer ID?
