Yeah, it's tight, but it isn't "worse than a coffin" -- the console closes toward you, and the screen is about a foot from your face, but there's plenty of space to the sides, and the console has to be close enough for you to push your mission task switches (and play with all the others).
Besides, if you're following instructions -- and I recommend following those instructions -- you won't be turning your head from side to side while the ride is running. Instead, you'll be staring at the screen, which, if you focus on it, takes on the appearance of a window offering a view "outside" the "spacecraft."
If you can suspend reality enough to buy into that illusion, you'll do just fine.
If you still think you'll be bothered, try using your computer with your face about 12-14 inches from the display. That's the approximate distance. Imagine your display is a window through a space ship bulkhead. Do this until you are no longer anxious about having the display that close to your face.
If you do that a couple of times a week, you should be fine by the time you decide to ride.
