@caseyliss Nice post. Another reason, which I might have missed, is that by using CarPlay all of my data is in sync. Apple Maps remembers all my stuff and is useful when I rent a car. Overcast knows my podcasts and what I've listened to, trying to keep track by having Overcast and another app on a car would be a nightmare. Plus privacy issues.

My car is my iPhone's most expensive accessory. The iPhone is not my car's accessory.
