The Americans in the fifties produced some amazing concept cars and one of the most outrageous was the 1959 Cadillac Cyclone. Of course, being a Cadillac, it had to have lots of bells and whistles. The bubble top is electric, as are the doors, and the top can flip back into the boot to make it a convertible. Those out-there nose cones house radar sensors to alert the drive of any obstacles on the road ahead. It also has an intercom system to converse with people outside the car without having to lift the canopy! Cheers, Shorty.
