Touchscreen controls are crappy. They're less nice than ugly buttons.
(And of course people still buy cars with flaws. An entire car is an amalgamation of so many features that's it's hard to use purchases to measure people's reaction to the vast majority of specific changes. And features like controls often take longer than a test drive to evaluate, too.)
