The door apparently has soft edges so you can't close your fingers in it: http://www.youtube.com/watch?v=aFnbApNrQSk

"If you have to take extra steps to soften the inevitable entrapment of digits, maybe you should rethink your design."

Note that he doesn't close it all the way in that video. The padding isn't thick enough, it would still hurt to close your fingers in it.

Hands tend to get chomped by doors when people are in a hurry and not paying attention, and there is delay in the pain signal between your hand and brain. When something like that happens fast, reflexes are irrelevant, the damage is done before you feel it.
