The cars sell because that's what the customer wants (as opposite of what EU wants customers to buy/rent/share). There's not a single ordinary brand new car sold in EU that I'm interested to buy if I could afford. Cars used to be fun until 2010-2015 something (when instruments were still tactile and less "automatical" features were obligatory) - I do not want to pay for e-call, automatic lane assistant and so on. Might pay for rear camera and parking sensors though.
There's lots of things that are not needed, but that are desired. I do not need a huge pick-up truck, but wouldn't mind a car with a great ground clearance and wheel base. I do know lots of folks that need big pick-up trucks that wouldn't agree on "engineered need". Perhaps you live in a big city?
