Some ideas on better elevator design

The modern safety elevator was invented by Elisha Otis in 1853, but in spite of its long history, many problems remain: they're slow, and their design encourages inefficient use, which makes them slower. Here's how elevators should work, and why.

• The floor selection buttons should toggle: press once to set, press again to clear. People commonly hit the wrong button, but there is no way to undo that mistake, and it slows down that trip to stop at a floor unnecessarily. The button should light up to provide immediate feedback that it's set on. It can also beep to help those with some visual impairment.
• The buttons should not be located only by the door. Currently, people enter the elevator car, press a button, and then stop moving, blocking the doorway and access to the button panel. If the panel were in the back or the side of the car (or all three places), there would be fewer clumps of passengers at the front by the door.
• The door should open very quickly. They can close more slowly to avoid crushing limbs, but there is no reason they can't open at double-speed or greater.
• The doors should be transparent. This would allow people waiting to enter the car to see if passengers are about to exit before the car comes to a complete stop. It allows the converse opportunity to those inside waiting to step out.
• The doors should be the full-width of the car to avoid creating an exit bottleneck.
• The elevator should emit white noise on the standard cell phone frequencies to render those phones inoperable within the car. Okay, I'm kidding—but I can hope, can't I?
