There are other solutions besides crazy expensive vandal-proof high-tech toilets. Just look at what they do in Europe.

* Large Public restrooms in busy city centers and transit hubs where you have attendants constantly cleaning the place and charge people to use the facilities.

* Outdoor public urinals that are little more than a drain and a shield. This is an 80% solution that solves the problem of stinking alleys. Much of the time men just need a place to leak during a night of drinking. Women are way better about finding and getting permission to use private restrooms at shops/restaurants.
