I now and then check Tesla share prices after that kind of bad news - and to my amazement it just keeps going up.

That they're not really good at the car building part has been well known for quite a while - and by now it should be blatantly obvious even for people not doing software stuff for a living that they're also not stellar at the software thing (which I assume their valuation is mainly based on, as it doesn't make much sense). They are better at least with the infotainment software than established car makers - but given how those suck at it that's really not hard.

I don't really see them spreading too much in the EU currently - they're currently trying very hard to piss off the Nordics, and I'd expect to see regulation eventually prohibiting new cards with touch only controls. It already is treated like a mobile device by law here - so touching any settings on your Teslas touch screen while driving can be very expensive, up to a temporary loss of license. Also having an accident while touching the screen will shift more of the blame to you.
