How exactly are they unsanity disasters? I would much rather use a urinal and never need to touch anything (besides myself, which unless I myself am unsanitary that should be clean) than need to either sit down and make contact with a surface a bunch of other people have made contact with or need to lift down and raise a lid to use that if I am standing.
Looking online I can't find anything about how they are any less sanitary than just a public bathroom is to begin with.
Unsightly, maybe, but I don't see how they're unsanitary. Urine is nearly sterile.
If you're standing up, it's also a lot easier to "hit the target" into a urinal vs. a toilet. Having a bunch of people peeing standing up into normal toilets would be a lot more gross than urinals.
