Touch screens don't have to be modal, that's a UI choice. The 2020 Bolt we just got leaves the climate controls on screen at all times, even when CarPlay is open. I was also pleasantly surprised by the number of buttons it has, including both a volume knob and a temperature knob.

That being said, the touchscreen software is abysmal and laggy. CarPlay works great, but any time I have to navigate the car's built-in software is a headache.
