and what about the bathrooms? Can they make them with see through walls? I'm serious. could they have it so when seated you have privacy but otherwise we have a clear view of what people are doing in there?
And timers are needed too. Unless you have medical/bowel problems of some kind, you shouldn't be in the potty very long. This may be something to consider.
Frosted showerglass in a bathroom. The stewardess can observe that you aren't messing with the walls.
I've been thinking about the restrooms too. They need to become much safer. Timers are a good idea. Don't know how to handle the privacy issue, but I hope someone somewhere is working on it.
There are public toilets on the streets of some cities that automatically open the door after Xminutes.
In part to keep junkies from using them.
Perhaps some kind of camera set up so that other passengers can watch you in there using their in seat tv screens.
Also perhaps a microphone. Perhaps an air marshal hidden in a false wall?
