Chrysler Concept 70X -

The Chrysler Concept 70X is a concept car from 1969.

It featured parallelogram doors similar to those used on today’s minivans. The interior contained a small ultrasonic electronic device that was 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. When a vehicle entered one of the swept zones, a red warning light lit up on the mirror, often giving as much as .04 seconds warning before impact.
