> I really enjoy these interactions, but I feel for the drivers, it’s a very tough job where most taxi drivers have to scramble to find places to urinate or do so in an empty bottle between their legs.

Public toilets, their condition and their non-existence are an often-overlooked issue! It's not just highly problematic for taxi drivers, but also for parcel and postal delivery people... and it's not just relevant for workers either, it's also (IMHO) a violation of anti-discrimination laws.

Imagine you're old and don't have much bladder control or volume, or you're a woman who recently has given birth, or you got one of the variety of bowel related diseases, or you've got a child who is still dependent on diapers. Your range of free unimpeded movement is basically limited to where you have easy and fast access to a toilet or at the very least a place to take care of yourself/a child.
