Transitions are difficult. Available new technologies are expensive. Because of that, profits can be reaped. And in laissez faire economies, competition springs up to compete for those profits.
So. You walk into any women's public bathroom in America now. You encounter four devices:
-a soap dispenser
-something that dries your hands
Invariably, they all operate on different assumptions, are made by different companies, and have different points of failure. The toilet self-flushes. Or you have to actuate the flush. The faucet works when you wave your hands at a sensor. Or you push down on the top, or you turn handles. The soap dispenser either needs a solid push, or another wave of a hand near a sensor. And the drier either needs a push on a lever, a turn of a wheel, a wave at a sensor, or a dip of your hands into the U that blows you to deafened oblivion.
And NONE devices that work by sensor reliably works. You are waving at faucets, cursing the faulty technology. You look down. And see that you have to push down to get the water running, and now you feel like an idiot. Or you look for the lever on the towel machine, and after fruitless searching, understand (with people waiting behind you), that it is the sensor that needs to be waved at. Or simply? The sensor isn't sensing.
The worst is when the toilets are auto, refuse to flush, AND the rescue button doesn't. What now?
It's enough to make a reasonable woman want to hold on until her bladder busts.
