Automatic Restroom!

     It's wise to be sanitary.  Well, most of us think so.  When it comes to public restrooms, you see lots of auto-flush urinals & toilets.  You see sensor-operating soap dispensers, sink faucets, and hand-dryers.  You see sensor-activated lights, when you enter (to be energy-conscious).  Why hasn't somebody introduced automatic restroom doors?  Do you know how many people don't wash their hands after using the restroom?  Or how long germs linger on a doorknob?  Regardless, it always struck me as silly to have so much automation within a restroom but fail to have an automatic door (like a frosted glass version of the kind you see at supermarkets).  Big hotels and high-end eateries can afford it; they have heated toilets for crying out loud.  
     You avoid touching things all around the inside of the public restroom, only to touch a dirty door before you leave.  That defeats the whole purpose!  At least make sure all restroom doors "push" outward, so you can use your shoulder to open the door without touching it.  It's even nicer when places use a bent corridor, instead of a door at all.  I'd like to see an auto-doorway in the next "modern" building... to match its restroom's other auto-accessories.  That just makes sense.
