My issue isn't with Waze, or even CarPlay itself but how it is integrated in to at least VW's infotainment systems. As an example, if I have my phone connected via Bluetooth, I can use the steering wheel controls to go to my phone on the screen in my dashboard cluster where I can scroll through my recent calls and call my girlfriend for instance without removing my hands from the steering wheel or averting my eyes off the road too much. When my phone is connected via cable and using CarPlay I cannot do this at all, I am forced to remove my left hand from the steering and avert my eyes to my radio where I have to exit whatever it is was being displayed to access the phone app and start a call to my girlfriend.
This is the case for any car.
You are meant to press the Voice Assistant button and then say "Call my girlfriend".
It is the most powerful feature of car play...not having to fiddle with buttons and looking at screens while driving.
And then to take it one step further, while the call is connecting or I am on the phone, I cannot go back to Waze without the call being ended so 'multitasking' is impossible using CarPlay.
This is a Waze problem at present I believe and I don't think it happens with Apple Maps, so will hopefully be sorted in future.
Perhaps I am being pedantic but the functionality offered by just the simple Bluetooth connection far outweighs having an app like Waze on a larger screen than my iPhone 7 offers.
I'm the other way around where the Bluetooth connectivity feels so old school and limiting to me, especially since I can't access Siri over Bluetooth which is just stupid and could have sorted out half of my issues with it.
Bluetooth has the advantage of not requiring being plugged in, which I realise is because of battery drain and would be solved with Wireless Carplay in future but remains irritating.

My biggest issue with the Kia implementation and probably more the fault of just the infotainment system in general is that it defaults to playing the Radio when disconnecting from stuff or not being forced off.
I have no interest in the Radio EVER. Why on earth would it force me to listen to it instead of STFU and waiting for me to tell it what to do?
