The Spy Who Loved Me (1977)

Bet you didn’t know submarine cars existed in 1977. Okay, fine. They didn’t. But they did in the 1977 James Bond film The Spy Who Loved Me. Fun fact. Before Bond drove his iconic Aston Martin, he drove the Lotus Esprit Submarine car. Pretty cool. In 2008, sQuba, the first car that can actually "fly" underwater, was invented by Swiss engineering specialist Esoro. The car runs on natural gas and has zero emissions.
