As a rule, glycols are flamable. Hard to believe, but I have seen a couple of fires from
antifreeze. Glycols are also difficult to clean up on asphalt, very slippery as I'm sure you have experienced. So NASCAR bans them. Water is basically safe and inert, no problem.
This no-water system has been around in several variations for quite some time. I doubt that MECCA was first, but they did a lot of development with it. Desicants in the air vents from the overflow tanks, waterpump flow rates, radiator designs, developments in designs to take advantage of the high temp ranges. Smokey also used something similar. As well as reverse flow (which makes a lot more sense if you think about where you need to cool the most).
NASCAR isn't cutting edge in most areas, just the most finely deveoped antique technology you can find.
