I just had my first flight into IAD a few weeks ago and I think the mobile lounges are kind of weird.

They first reminded me of the vehicle they used on some TV show that was a futuristic kid's program on Saturdays (can't remember the name...anybody recall?)

Once on board, it seemed like a subway car that had been suped up with a Monster Truck/Off Road Wheels thing going on.

What happens when one of those remote terminals needs to be evacuated...everybody runs out onto the tarmac?
