If you’re a president, it’s important to make sure you get from A to B in one piece. While a white Range Rover may be more than sufficient for the average Youth League president, the leader of a superpower needs something special. It needs to be a substantial improvement, for example, on the 1961 Lincoln Continental four-door convertible sedan that was President JF Kennedy’s last ride in 1963. Cut to the present and America’s President Obama isn’t taking any chances in the back seat. Cadillac One, the Presidential State Car, has five-inch-thick armour along with bullet-proof glass. Its doors have that solid feel and weight of a Boeing 757 cabin door. Since the cabin is sealed (air-tight and soundproof), roadside cheering is conducted via an exterior microphone to on-board speakers. In the boot is a blood bank with President Obama’s blood type, along with a self-contained oxygen supply. There are more advanced features, like a fire-fighting system and an integrated weapons system with grenade launcher, but the exact details are classified.

As good as Cadillac One appears to be, those in the know know that there are even better, more advanced vehicles out there. There is, after all, far more to automotive excellence than merely staying alive.
