The point is that everywhere outside of the powerhouse first world economies runs on second hand cars imported from those economies. I'd know - in my country most cars are ex-german cars. And then once we're done with them, they go to Ukraine(or they used to). Then after that they go to far east or Africa. Your 100k mercedes has 15 lives before it gets scrapped.
But you know what stops that chain early? If everything in the car has subscription and strong encryption to prevent messing with payment options, which "incidentally" will mean those cars can't be worked on by anyone other than the official garage. Wouldn't want anyone to pirate some subscription-only stuff now, would we.
I'm not mourning rich people wanting to drive fast - I'm mourning regular folks who will get these cars at 15-20 years old and find out that the heating seats don't work because Mercedes won't enable them on a "legacy" vehicle. Or it's from the wrong region so they can't do anything for you, sorry.
EV cars are most likely not going to be exported to have a second life.
Well, that's absolutely inevitable given how things are going. It might not be in the next 10 years, but in 30? Almost certainly guaranteed.
What reason do you have to believe that?
mercedes isn't selling baby formulas or epipens
plenty of other brands will take your 100 years of 3rd world salary to give you some shiny vehicle
should I cry for some pampered millionaires who just want to drive faster?
