The first 24 Hours of Le Mans in 1923 started under hail and heavy rain, with cars with no roof, fragile headlights that would easily break with any small rock hitting them (also poorly isolated electrics from the water), no wipers, bicycle tires, tin can bodywork, on a barely paved track with lots of loose rocks, with very few lights, no barriers of any kind, no runoff areas, with drivers wearing leather aviator caps and goggles as the only kind of protection.
Yet, they soldiered on, going slowly in a line at night following any car with functioning headlights if necessary. How the fuck have we gone so soft as a society?
