Even before the application of windscreen wipers on automobiles, the need for a means to clear precipitation and muck from the windows of streetcars saw some interesting developments come to the fore. In 1903, Irish-born inventor JH Apjohn gained a UK patent for a mechanism that moved two brushes top to bottom to clear the windshield. Across the pond, US inventor Mary Anderson had to leave the front window down or stop to clear the snow from the panes on a streetcar ride during inclement weather. She came up with the idea of a swinging arm fitted with a rubber blade slotted through the window frame.
I am going to address the elephant in the room up-front. Citroen can make some pretty unusual, a little weird, “out there”, call them what you want, designs, and the Citroen DS is a classic example of this and is a strangely-popular vehicle. The DS model is the one you see driving around occasionally; you first look at the car — perhaps, no doubt with mixed emotions — then, look to the Driver and always wonder what they must know which you do not.
