Car manufacturers should get out of the dashboard design business. Just have an API standard for devices to control the car, and a USB port for users to plug in whichever device works best for them. You want a bunch of physical buttons? Cool, go down to AutoZone and buy a button panel that matches your needs. You want a big screen with carplay and a bunch of widgets? Mount your old iPad there.
The regulatory side would be the hard part. Devices would have to meet some safety standards and the car would have to refuse to drive unless an approved dashboard was connected, but it could be done.
