1959 Cadillac Cyclone
Peter Harholdt

Those are the radars for the car’s crash-avoidance system, a technology you might recognize as today’s adaptive cruise control. If the car sensed an approaching object, it would set of a series of warning lights and a high-pitched beep, and car could even automatically apply the brakes.
