you don't even know under what condition CM holds true

you don't have credit to discuss further with me. Why the heck on earth not those race cars are made out of titanium, why the heck on earth they are made cash-able? Why don't you tell them you are smarter than them, they should use titanium throughout. Why don't you weld the toughest steel on your car all around, dump your insurance, you never need it.

It is not worth wasting my time on talking to you. Enjoy the dilustion of you being smarter than the race car engineers and experts.
