As we all know the president of the United States always travels in a security convoy of black SUVs. Apparently some of those SUVs are outfitted with this pop-up gatling gun capable of firing 4,000 rounds per minute out of its six barrels. This is one car you don't want to cut off on the road and piss off the driver.
