I regularly drive my ancient Bronco 2 and sometimes a newish car with the touch display. I spend less than a second glancing at any control on the Bronco. It's so bad on the touch display I sometimes have to pull over to figure out how to get the fracking defroster on. It's even impossible to tell if it is on or off, you just have to wait and stick your hand on the base of the windshield. In Seattle having a working defroster is "flight critical" as they say. It's not a joke, but the controls are a joke.

BTW, "defrost" is a verb, and pictures are for things, not verbs. So I never know which stupid icon means "defrost". Lack of verbs is why picture written languages evolve into phonetic alphabets. I predict in 20 years Apple will announce a great breakthrough in user interfaces - words!

BTW, I have no idea what a defog control does that defrost doesn't.
