The attached video is very interesting and informational. It's about the president's limo driver. You've never seen anything like this before. When you take into account that the Secret Service limo driver for the president is driving a 12,000 lb. automobile at speeds up to 60 mph and in reverse over a one-mile course, it's even more amazing. This car has about 800 horsepower. The vehicle the president uses is weaponized and has a totally independent air conditioning system with its own oxygen supply in case there is any sort of aerosol poison in its vicinity. This video was filmed at Lime Rock Park in Connecticut.
