While I was driving around Europe this summer I often stopped somewhere, detached the phone from the holder and took some photos with it, then went back to the car and continued navigating. Also, I used Notes to write some notes and instructions beforehand and then quickly checked them along the way - stuff that didn't quite fit in Drive and its Favourites. Thus, my choices were not only "things I use inside the car" but also "things I use during a car trip". I do understand everyone may have completely different needs and I'll come up with a GUI to easily change them.
