First, they are talking about a 221-car sample; that seems extremely low and looks like it has been cherry picked from among all the possibilities to make Tesla look as bad as possible. Second, we are talking about Germany; a country that has a whole political arm related to building and selling car, in particular luxury, a segment where Tesla has been beating them in some factors recently. You can feel the bitterness through the screen. Third, I would expect a 10-year-old car manufacturer with brand new tech to have reliability a bit worse than an established manufacturer with old proven tech. But they don't even talk about the real cost or total cost of ownership anyway, so it is like guessing and comparing.
And they tout WV as reliable, which is kind of funny as everyone who really has own a WV will tell you, especially after the cheating scandal. I guess they are reliable as long as you don't care about electronics... And the electric Golf they are mentioning is not even produced anymore. My father's partner had an e-UP and was extremely unhappy with it so...
It seems like classic Tesla hate and I don't even care because I think most people should not even get a car or that a car at those prices do not make sense. But if you are going to spend that much money on a car, Tesla is hardly the worst choice...
