By 1940, Buick added the self-canceling mechanism attached to the steering column as standard equipment. This complex and sensitive mechanical method of springs, cams, sliders and lobes with fixed shut-off points is the basis of what is still used worldwide in virtually all vehicles.
It would not be until the late 60’s that the emergency 4-way flashers became standard.
The solid state technology in today’s cars don’t really need to make that clicky noise, but has remained a remnant from the olden days when bimetallic springs and little electronic under-dash chips and relays did all the work. Today, the clicking noise is added intentionally though the speakers or other means.
