Not here they aren't: A) No light source by design. Why do you need one? To read a newspaper? B) Have maintenance staff (for bigger ones) who actively prevent this and are paid (a pittance) for it - they also collect token pay for the use of e.g. shower. This also provides a few low paid jobs, reducing the problem. C) Expensive? Come on. Look up the costs of a portapotty first. We're living in the world where public buildings are finished in marble and chrome... D) We do not have huge drug problem in the first place, so people do not shoot up. Of course anything with nonzero cost would get labeled as expensive, it's a funny world we live in. Roads are more expensive than these. Any sort of public transport. Heck, pavement.
