Not really “rare”, outside of it’s niche, but definitely unusual!
I owned a 1969 Volkswagen Beetle, with an electromagnetic clutch. Instead of a clutch pedal, you pressed down on the stick and shifted it up/down, releasing once in position.
Not many vehicles used that particular style of clutch, and that was one of the last years VW built a model with one, as far as I’m aware. Miss that little car.
They might not be the fastest or prettiest, but old Volkswagens were reliable and stupid simple. Still hope to one day get my hands on an old Microbus and a Karmann Ghia.
