ERF-NGC-European:
I never had any problem with the floor-mounted dip-switch. All my early cars and vans had 'em, starting with my '54 Moggie (I always ran old bangers). It was tempting , if you were tired, to use the dip-switch as a clutch. I have to say, when the dip-switch did eventually migrate to the column stalk I found it more convenient.
I’ve often pondered the idea of a thread on appalling ergonomics of lorries of the '50s onward 
and I think someone should start it.
After you, of course
