DAF Mobile Raincoat, designed by Hub van Doorne in 1943, could literally drive through a front door thanks to its single front wheel and narrow build. This oddball Dutch car was built to hide from Nazis and later starred as a clown car. “Looks like an oversized roller skate,” quipped one observer.

Originally crafted to sneak indoors and avoid Nazi confiscation, the DAF Mobile Raincoat boasted a fabric roof and could reverse at full speed by simply swiveling its lone front wheel. Eventually, it became a circus staple, leaving muddy tracks and baffled parents in its wake.

The DAF Mobile Raincoat could drive as fast backward as forward—just by steering its single front wheel in reverse.
