I Haven't Seen One of These Cars on the Road! This could be a perfect combination of a futuristic and vintage car. Even though the Citroen DS was invented in 1972 by Michelin, most of us have never seen this type of car on the road. The reason for that is they were not used as family cars, but instead used to test tires for large trucks. This car was so heavy that if the driver had a blow out, he or she could still be in control of the car, unlike a truck.
