One complaint about Android Auto (and Apple CarPlay) that sometimes gets lost in the shuffle is app access. There are a few ways of forcing apps into Android Auto, and some genuine benefits if everything works out.

All this might be worth the hassle if it weren't for the fact that Android Auto is rapidly evolving. The rails on Android Auto mostly exist for sound reasons, including preventing drivers from getting distracted.
