1969 Chrysler Concept 70X

Chrysler’s Concept 70X concept car featured parallelogram doors similar to today’s minivans. The Interior contained a small ultrasonic electronic device mounted next to the rear seat speaker. This component swept an area 50 feet to the rear in three zones: left lane, right lane, and immediately behind. A red warning light lit up on the mirror when a vehicle entered one of the swept zones, often giving as much as .04 seconds warning before impact.
