Here are two cars from the exact same year (Toyota 7 and Chapparal 2J), yet the drivers wear different gear. The driver of the Chapparal wears the old style gear, but the driver of the Toyota wears modern race gear. Can someone tell me why this is?
Perhaps one thing to take into account is the differing in country and then culture, perhaps the Americans hadn't adopted the modern gear yet and the Japanese already had?
