Compared to the population of the world, only a few people are able to drive a Mercedes-Benz, Audi, BMW or Lexus - yet they are built with some sort of comfort and perfection in mind.
Everyone of these 6,6 billion people out there, however, needs to go to toilet. Every day.
I wonder why ppl spend so much money on good cars and other items but actually never really think about improving their sanitation needs. Same attitude applies to ppl using public toilets. How come many people often don’t care about clean sanitation facilities?
