My mom she has a Honda Jazz and the UI is one oft the most terrible from all cars I have seen so far. A few things at least like Audio volume, some radio channels and temperature should have hardware knobs or buttons, so I easy can change it without looking on the screen. Then also should be a place under the screen where i can rest my hand (like has something, at least in a new car I drove recently), so I can touch the screen with a single finger multiple times on the same spot without looking on the screen.
