I don't really mind having less buttons to accidentally push on my phone or other devices that go in my pocket, but I can't stand this when it comes to car dashboard interfaces. Thankfully I still drive a car from before this trend but in newer cars where e.g. changing the radio station requires fiddling with a touch screen. With physical buttons or knobs I can do this almost unconsciously, but with a touch screen I have to take my eyes off the road to even see what I'm poking on the screen. With this kind of stuff, it always makes me wonder why it's there in the first place. Surely there's not much demand for touch screens in cars, and it must be more expensive to produce than analog buttons and knobs. Why has it become so ubiquitous?
