I believe the anti-sex features are actually anti-homeless features because toilet-sex probably is not that common + it does not cause many issues when it does happen.

What is the detection of violent movements for of not the sex detection? I assumed the homeless would try to sleep resulting in closer to no movement. She goes for the weight detector that's supposedly there to see if two people are in there. The homeless issue could really be solved by a generous time limit.

The UK still arrests people for “cottaging” (i.e. men suspected of having clandestine gay sex). For example: https://www.diversitytrust.org.uk/2019/02/arrested-for-cotta...

In clubs it's less about sex and more about catching people using drugs. Some places will take the doors off bathroom stalls so they can catch people.

some smear vasilene over all the horizontal surfaces so no drugs can happen easily.
