It seems that from the dawn of auto racing, the sport worked to "improve the breed". The way I see it, running at continuous high speed in a counter
clockwise direction, is a good way to improve food mixers, but adds little to automotive engineering.
But by the same token, when cars are stressfully run in all conditions..rain, snow, ice, hills, mud, sand, left and right turns, up and down hill,
all through any of the 24 hours of darkness and light, may well by experience, help to make better automotive designs.
Sure, running in a dry bowl...keeps any admission prices all to the producers of the race... no free spectator positions..and they must buy the costly
refershments at exorbitaant rates, from the same source.
Probably the nexus of all left turn only racing...
