Back at the Dawn of Time, there was at least a modest reason for wearing driving gloves. Steering wheels were huge smooth plastic spindly things not given to providing the most secure grip for "sporting" driving. At least that's what we told ourselves.
The true sporting driver opted for a wood rim wheel
and the string-back gloves, 'cause that's what the pictures of Stirling Moss at speed always showed.
Truth be told, it was always pretty much stylistic nonsense, not unlike a bunch of carbon fiber trim and ground effects kits on street cars today.
