Why does CarPlay need WiFi?

Why does wireless CarPlay need WiFi. While my vehicle does have a hotspot I do not have a data plan for it.

Also, when I setup CarPlay it asked me to enable wireless which I did but it never asked for the Hotspot password.

I don’t understand.

Thanks in advance.
 
It doesn't need a Wi-Fi network with data or a hotspot. It just needs Wi-Fi enabled so it can connect to the CarPlay network. It's essentially a wireless ad hoc network so that the two devices can communicate.

Connect iPhone to CarPlay

Set up CarPlay by connecting your iPhone and your vehicle using your vehicle’s USB port or its wireless capability.

If I turn the hotspot off in my car (GM) wireless CarPlay does not work. However I get the adhoc network idea. There are other devices like that.

Thank you.
