Living in communism we did not have coolants available, so lot of cars drove on water. It was annoying in winter, when you had to drain it for every stop longer than 2 hr.
Couple of my friends pour diesel in cooling system to avoid the hassle.
That was in cold climate so perfect heat exchange was not important and cars did not last long, so long lasting radiators were not important.
So regardless how badly some MB owners feel about violating the rules, water will not kill the car, but use distillate water as tap water will deposit boiling stone.
Another myth is coolant poisoning. Years ago my friend work on my yard at his car and had coolant in pan on the ground. 2 neighbor dogs jumped the fence and drunk most of it. Later on neighbor gave one of the dog to us and she lived happily till 16, what is good age for German Sheppard.
