I totally agree that when you are driving you should be driving and nothing else. Even fidling with the radio is dangerous. However the vast, vast majority of people do fiddle with stuff. We can't even get enough people to stop using their phones to keep it from being a fatal epidemic. So if it is present, people are going to use it, and because it's geared highly toward usability while driving you can forgive them for thinking it should be fine because clearly the manufacturer thinks it is.
