Here are few details that I think worth noting:
The standard does not "specify motor capacity" it establishes procedure for rating of
electric drivetrains.
My interpretation is the same as JB Straubel's and Tesla Motors Engineering, but arrived at independently, prior to JB Straubel's Blog post. The interesting part is that some members active on the threads relating to "missing horsepower" were aware of this regulation for quite some time, but, apart from Stopcrazypp, they did not care to carefully read through it, apparently because there was nothing there to support their views.
Your bullet list, aside from the
first bullet that I addressed, has nothing to do with the Standard, just with the fact that you don't like it.
