Better yet, Require the only test that matters in an EV: Range at 70mph on a real highway.
It is difficult to find a good solution for this, even providing 3 ranges (city, suburban, highway) has its limits and will confuse people.
But anyway my point is that this combined number is meaningless and unhelpful even in that case. Highway provides a minimum number. Any other test just produces confusion and disappointment.
... Or if the stakes are high enough, building their own "test track".
I simply do not understand why a comprehensive set of basic tests aren’t performed, and I assume that’s my own ignorance. But I’ll say my opinion anyways… It’s not like creating a new car doesn’t cost a billion dollars. Is it really unreasonable to have a test suite that gives consumers accurate information across a spectrum of driving conditions?
AND that would FINALLY represent a significant gate to “cheating on the test” as it wouldn’t create the “single test” paradigm that’s clearly not possible for manufacturers to follow.

39 out of 50 (or 51, if you count DC as state-like) states have maximum posted speed limits of 70mph or higher, which is a very clear majority.
