Fuller is probably one of the more overrated intellectuals of the 20th century. His greatest talent lay in self-promotion. He was not a competent engineer, architect or scientist. His one good idea wasn't really his (geodesic domes had been patented in Germany decades earlier) and he required the services of an actual architect to get anything done with them.
He provided one very important thing (at least to me): an optimistic view of the future and our ability to support ourselves.
Tucker is probably a pioneer in safe car design. It had a roll bar and reinforced sides. The windshield was designed to give way when struck from the inside, lessening the impact on the occupant in forward collisions.
The person who invented safe car roofs is completely anonymous but i had to hear all my life what a genius Buckminster Fuller is. For doing what im not exactly sure but im supposed to admire him.
