You fail to say that while they may have the highest satisfaction rating they are also the least reliable. You seem to ignore the fact that Tesla has amended the warranty that now includes once covered failures in area that Tesla totally fails on, body, interior and cosmetics.
There is no comparison to Porsche and many others, they are in another universe. Porsche has been building some of the most iconic cars ever made for over 70 years.
You have made the claim that for an ev a car that is designed to be an ev needs to be a ground up design while failing to mention that Musk bought the Roadster as a Lotus Elise knock down and did an ev conversion.
Tesla sure seems more like the cell phone Nokia and Ericsson, they were the absolute tops in the field with high return stock prices until other companies got into the game.
Letting Ford and GM use the charging stations may cause some real friction with Tesla owners, it could get real interesting.
I am not interesting in going back and forth with you, the point is you are a fan with your free electricity perpetually promoting these things that are not all they are cracked up to be.
