Everyone was fascinated by jet fighters and it made its way into car designs... from hood ornaments, design elements, and to fins.
Many US car enthusiasts remember the Chrysler Turbine car. It was (per ledgend) the inspiration for the original Batmobile. Most have never seen Fiat's Turbine car, a beautiful car even w/o the unique drivetrain. Consider that development began in 1949, it wasn't the first but certainly prettier than the others.
This is Rover's 1950 car vs the 1954 Turbina. Parphrasing BTTF, "The way I see it, if you're going to build a Turbine car, why not do it with some style."
