Not even just for the driver to be touching it, but if you have a passenger you can let them deal with putting in directions or managing your audio and the wheel is a lot less obvious than a touchscreen to someone who isn't familiar with it.
And as a driver, it felt like there were some things where it'd be easier to just touch the screen too. Like for the buttons scattered around the corner of Maps, scrolling through a list or a grid is easy to navigate, random stuff all over the screen you'll have to learn the order.
Apparently the Japanese market version for 2024 is getting a 10.25" screen which I'm guessing is the same part as the CX-50. That could mean adding touch for CarPlay, but none of the articles mention it one way or the other. Maybe I'll wait and see about the US update before making any buying decisions.
