The act of presenting ICE and BEV variants allows an observer to 'focus' in on the existing variations which lead to the differences, in order to parse out the specifics. I see no harm, only the contrary.
Isn't the point though? When the focus is specifically targeting cooling drag it is impossible to compare a cars cooling drag by looking at its Cd in ICE and EV form. You can't get the specifics of where the change comes from, that cannot be extracted from the data and so how can it allow the observer to " 'focus' in on the specifics" ?

If I modify my car, and change the cooling system, the undertray, the wheels and the rims and then say "I have lowered drag by 10%", you don't know which mods did what amount of the change, some could be increasing drag, some could decrease.

I see the interest in the comparisons, and thanks for providing them, but I disagree completely that you can get specifics from a Cd change.
