Obama-Mobile Cadillac One

At last, the soon-to-be american president Obama will finally have a car Batman would be jealous of, and that even Jack Bauer would be proud.

Beside 8in thick doors, it can withstand rocket impacts and is completely sealed from the exterior to prevent any contamination to the inside in case of bio-attacks.

And at 8mpg, you can't say it isn't ecological enough (for such a "tank") - though I'd expect its next generation to be an hybrid, fully electric, or hydrogen powered vehicle to keep up with a greener world. ;)
