Fallout indeed. But I wonder about the method of entry. No doors or seams, no nothing. I would imagine You climb into it through a hatch under the car, which would make it rather practical indeed
Also, no boot for luggage, unless the entire top of the car lifts.
I'd rather take the stunning Cadillac Cien as long as we are talking about one hundred per cent American cars. That, the boat and Scarlett Johansson were the only good things about The Island.
There was a contest recently where all the big auto makers designed a car that would be able to drive around the world in a race. The image you quoted is only one of three modes that the Mazda car had. It also had a boat mode and a jet mode. Specifics for the race were something like, "You have to be on wheels in America, in the air through Europe, etc". The thing looks fucking siiiick.
