This sounds a bit far fetched, but the article has enough good points to make you think there is a possibility. There is a lot of theory this far and no prototypes mentioned. However, they refer to many technologies that are already available and the way they might fit together to accomplish the goal.

We are used to seeing inflatable vehicles for water. A great website to see examples is - http://www.seaeagle.com/SportRunabouts.aspx

If the XP vehicle is built tough enough, there could actually be some gain in protection for the passengers. Airbags would not have to inflate because the vehicle would already offer some cushion from impacts.

From the article:
"XP's MUV does not consist of a lot of internal componentry. In fact, most of it is air using XP's XPanelB (tm) technology pressure membranes. The seat is inflatable, the dashboard is inflatable, and the internal structure and carrying racks are inflatable, or a mesh suspension. Instead of requiring six-axis robots, XP uses radio frequency welders that look like giant waffle irons. The factory equipment is much less expensive and the car simply has less parts that could fail.

The motors are built into the rear wheels in most XP prototypes. The first cars to reach the market will have two rear hub motors and a motor controller, that's it."

My guess is that steering will also be involved as well as a few other mechanical systems like door latches and seatbelts. I also wonder about windows. Will they be clear plastic that will need changed every few years like a rag top car of the past?
