Automobile designers and engineers have often pushed boundaries to make faster, sleeker, and more attractive cars. But sometimes that effort results in vehicles so eccentric that the world looks on in bemusement. 

These automotive oddities aren’t necessarily bad cars, but they certainly stand out for being well beyond the norm, whether it’s a vehicle so tiny it can fit through a doorway or a propeller-powered safety hazard. Here are seven of the most curious cars ever presented to an unsuspecting public.

Leyat Helica

In 1913, French biplane designer Marcel Leyat had what he believed was a brilliant idea: Why not put an airplane propeller on the front of a car? The result was the Leyat Helica — basically a wingless plane on wheels, with a massive wooden propeller mounted directly to the front. The first production model appeared in 1921, but despite some initial interest, only 30 were ever built. 

Leyat’s car had a few issues, but one stood out: It was spectacularly unsafe. The lightweight vehicle had rear-wheel steering, minimal brakes, a top speed of 106 mph, and a giant spinning blade where most cars would have a grille. Thankfully for pedestrians, pigeons, and anything else that stood in the way of the propeller-driven death trap, the Leyat Helica never took off.
