Lexus ES350h and also most of the new Toyotas do it right (except that Lexus model doesn't have fold down rear seats so it's just literally for senior citizens). The sanest use of touchscreens is to have it to display navigation and audio info but physical controls for volume, scanning, and all of the hvac shit.
Don't know why they're overthinking it unless they're going for planned obsolescence and being general cheapasses since touchscreens are cheaper than physical buttons
