As I recall, the drivers in the president’s motorcade, known as “The Beast”, are trained and able to spontaneously reverse direction in unison should there ever be a threat to the president that requires them to quickly extract the president and themselves from the danger.
The attached video is about the President’s limo driver.
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; in reverse, over a one mile course, it’s even more amazing.
This car has about 800 horse power.
The vehicle the President uses also is weaponized and uses a totally independent air conditioning system with its own oxygen supply in case there is any sort of aerosol poison in its vicinity.
