Apple’s CarPlay is still frustratingly simple.
Stephen Hackett at 512 pixels has blogged about the frustrations he had migrating to a new iPhone and not having his CarPlay preferences, despite having every other app on his phone copied correctly.
I agree with him, but I’m more annoyed by the second point he emphasizes: CarPlay still treats every vehicle you connect to as something different. Instead of keeping your preferences when plugging in a different car, you have to set everything up again for each new vehicle. This is annoying for families with more than one car; it’s downright insane for frequent rental car users. Seems easy to solve!
