Being able to travel for extended periods at speeds over 90 miles an hour is a vehicle capability only required by a tiny fraction of the total car buying market. I would estimate less than 0.1%. So extended high speed travel is a "feature" that is not required to be a successful car company.
I agree with you that when selling high end cars in Germany, EVs do not offer all the "features" required by many customers. But the German car market is only a tiny fraction of the global car market. And the percentage of all car buyers who want to track their street car is also tiny.
I have owned many Porsches. Over the decades, as you have of course noticed, Porsche has changed quite a bit and in fact was saved from bankruptcy, in part, by offering models that are not sports cars. And in the future, Porsche will have to change even more to survive, by offering BEVs.
