While traveling in San Francisco, we ran into the following high tech porta potty. You put a quarter in the slot, the door opens automatically and you step inside. Inside you hit the door close button and enter the world of high tech bathrooms. To wash your hands, you just hold your hands over the sink. The water and soap start pouring automatically and after a time, they shut off and hot air blows out. When you leave, the whole bathroom cleans itself, including the floor and toilet bowl. There’s a warning sign telling people not to enter as people leave, as the wash cycle happens automatically!
