alt Hacker NewsOP here: I always disliked touchscreens in cars, so I didn't understand why automakers kept shoving them in. I always assumed I was weird in some way, and that most consumers preferred touchscreens or something (Reddit seems to argue this in circles all the time). I planned to keep buying Mazdas, with their lovely buttons and stuff.
But when Mazda unveiled their button-lite 2026 CX-5 about a year ago, I started investigating.
I'm pretty convinced that touchscreens today are primarily a cost-saving measure, and every other justification is secondary. I hope I can convince you, too!

It amuses me that back in the 90's LCD color screens were magical fairy dust that cost about the same as what magical fairy dust would cost. Laptops with color LCD screens were like $6000 in the 90's, I think $3k over a greyscale. That's like $13k today.
Whereas the little plastic buttons and knobs were cheaper to pump out of an injection molding machine and assembled. Now screens are cheaper to make than little plastic baubles.

The article explained why. Since 2018 in the US, due to the proliferation of giant trucks being used as passenger vehicles (SUV's) backup cameras have been mandatory safety equipment. A backup camera requires a screen. So the automakers have to install a screen in the dashboard.
It is only a few dollars more to install a "touch screen" vs. a "basic display screen", and with the addition of those few dollars to the screen, that touch screen can now replace hundreds of dollars of physical buttons and their necessary wiring.
Net result, the BOM cost of the car drops by several hundred dollars, and the cost to assemble drops by some measurable amount as well.
So they why is: "because they save the automakers BOM and assembly costs".
I love the click-wheel on my Mazda3 and I love that it allows the screen to sit out of arms length up on the dashboard. Its a very nice interior. What I don't love is how Android Auto is slowly breaking since it assumes more and more that you have a touchscreen.
It used to be that it would focus buttons in notifications, making it easy to interact with. Now the focus doesn't seem to change at all (or only sometimes) making it a nightmare to do simple things. I dare not use the new Gemini assistant since the last time I was completely unable to navigate to the buttons in its panel at all.
I really hope they don't phase out the wheel just because Google sucks at supporting it. I know they have both touch and the wheel in newer models now.
The reality is they want to serve us ads in the future. But they first need adoption.
I think that nowadays people value "technological features", and how better to show "technological advancement" like a giant ass touchscreen and not some "old" XX century knobs.
It is so much easier to add internationalization to a touchscreen over physical buttons

I thought this is a pretty well-known thing already? For almost decade.
