Similar to the elevator concept, I used to fly a fair amount, and one of the places that I flew through had a tram from one terminal to the other. In this particular location only the doors on one side of the tram opened for both the folks exiting and the folks getting on. It was always a little bit of an issue, but the folks getting on usually "got it" when they saw the hoard of folks getting off and realized that they couldn't get on until we were done getting off. One time, it had been a particularly long day of travel, and when the door opened, there was a semicircle of folks completely blocking the door and pushing forward. I plowed between the two in the center with my carry-on being dragged behind me. I definitely made contact on both sides and felt my suitcase rumble over the toes and past the shins of at least 2 people. I felt a little bad afterward, but not that bad.
