great insght...
my 2014 Model S ($89K, 265mi range)) is a dinosaur compared to the 2020 MS ($69K, 402 miles range)...plus better tech infra. Basically i am driving an iphone 3.
still 98K miles and just wipers and tires...cheap to run.
FYI, the same story (Wrights Law) goes with rooftop solar, it becomes cheap enough that it surpasses the transmission cost of the utilities. DYI Solar is inching its way to this tipping point. I charge all my cars (telsa) and bike (alta) "from home".
