The committee members have years of experience in engineering, design and development work for the automotive and commercial vehicle industries. Listed below are actual test result and pictures illustrating the type of catastrophic failures that can and will occur using the wrong type of wire, such as welding cable! "

Most of the welding cable I've seen doesn't have any markings on it, so you aren't sure what it's rated for, not to mention it's larger in diameter. Then there's also EMI to consider. Why don't OEs use welding cable?

All I can say is use what you want, I know what I feel safer using. Just because 'it works' doesn't mean it's the best choice. There's a spec for auto use, why not do some homework on it instead of taking other's word for it? .
Racers have used Copper Welding Cable since the 1950s in their race cars.

Most automotive battery cables today are designed on the premise of "use the cheapest material that will pass the minimum specs to get the job done."

Copper prices have been high for years. The manufactures run durability tests to find the cheapest material and design that will pass the tests. (They ARE trying to make money on the cars they sell.)

Everything that you say is true but copper Welding cable is not inferior to OEM wire if used in a proper racing application. There are no cold temps, water ingestion, desert dust, or oily environments (if the engine is sealed up properly) to worry about.
