The Ford Seattle-ite XXI was a concept car designed by Alex Tremulis and displayed on 20 April 1962 on the Ford stand at the Seattle World's Fair. The car contained novel ideas that have since become reality: interchangeable fuel cell power units; interchangeable bodies; interactive computer navigation, mapping, and auto information systems; and four driving and steering wheels. The concept of some form of compact nuclear propulsion device was included as a possible power source on the assumption that radiation issues could be overcome without the need for prohibitively bulky shielding You can support me by subscribing to my [Instagram](https://instagram.com/dark_igorek)🙂
