Most cars I've looked at use an infotainment screen instead of push buttons for functions like climate control. This is why I'm still driving my 2014 vehicle.
It's unacceptable to have buggy and slow software controlling essential parts of the interior of a car.
Auto makers should throw out touchscreens and return to buttons.
