Sure I'm sometimes in a rush, but I think the deplaning process is fine, other than it's obvious multiple door deplaning would be faster.
IMO, if you're getting worked up over this you should learn to relax. As someone pointed out, often times you just rush and then end up waiting longer for the tram, rental car shuttle, etc.
I laugh at most people that try to rush out in a rude way as I end up passing most of these people when I speed walk through the terminal.
