I can see how this might have happened. Tessla was a big deal and had those horrible door handles and companies probably wanted to look innovative rather than have good working designs. And physical buttons are more expensive to put in and don't look nearly as futuristic. I heard an add for a car a few days ago on NPR that was literally just "it has 30+ inches of screens!"
But perhaps the story is more about consumers who just want new, exciting things like weird door handles and 30 inches of screens, who cares what they do, and the car companies just threw up their hands and gave them what they wanted? I don't know. I would love to know the full story. I'm sure its documented somewhere.
