Great post Mike!
I'm in the business and your analysis is very accurate.
Here's one that I'll add.
Manufacturers recommend only charging the battery to 80%.
All the mileage estimates are done at 100%
Be wary.
There's a lot of "smoke and mirrors " going on.
Also, before you buy an EV, check resale value of the model you are considering. Do not go by advertised "asking price" as most are selling for substantially less than that.
