I was driving an F150 with just a touch screen and it was much worse when I needed to find an item on the screen and try to touch it on a far-located screen in a shaking car.
In my experience, there is no advantage to pausing on some random icon I don't want. I always have to re-orient anyway. Tapping an icon on the screen is instantaneous. There's also some extra complexity in what grid of icons you currently have selected and how to move between them.
But that advantage goes away for any element that isn't currently on the screen. So navigating between pages or submenus or slide up drawers is much more fiddly than the dial and much more susceptible to the "car shake" issue.
