I don't really understand why the author is dumping on LA's toilets so much while praising how Parisian toilets are so useful for everyday people like commuters. The LA Metro program, which is expanding and seems to be very successful, has very different goals and challenges than the skid row public bathrooms.
Any "private" space in a public place becomes valuable with more density. It's basic scarcity incentives. It unfortunately incentivizes hooligans to make the restroom appear even more disheveled and unsafe to increase the privacy (less people want to go in it)
That is a fairly strong claim on the surface and the company's website has a slightly different one:
"In 1964, Jean-Claude Decaux invented advertising street furniture."
Such a fundamental mistake in the opening paragraph. Made me realize I could not trust whatever was written afterwards.
Uncorrelated with the usefulness of the building after controlling for other factors
