Friend of mine just got a new Volvo, that touch screen was such a UI/UX disaster it was just shocking. The number of touches it took to do anything was ridiculous. He was trying to figure out how to do something super basic, like it should've just had a dial on the dash basic, and it took minutes to find. I don't know if others are better, but that thing made me want to never buy a new car.
XC90? I'd say they have a pretty great touchscreen interface.. My favorite right now is from JLR (Jaguar Land Rover) with physical dials embedded into a screen - that can context change. [1]
I've had the updated XC90 since 2016 and while yes, the touch screen took some getting used to, I can now access everything I need quite easily. I really do like the clean looking interior.
I test drove a Porche Macan as well and it's the exact opposite of the XC90... literally buttons everywhere you look.
I guess the different interior designs attract different people. I really just prefer the minimalist approach with the XC90.
