Just place a phone/charging case on a Qi charger?
Doesn't CarPlay support wireless communication? Android Auto does.
Cars didn’t really start getting wireless CarPlay until around 2021. It would take a while for those cars to age out. My guess is that if Apple makes a portless iPhone, they will also make a wireless to wired CarPlay bridge.
There are already third party wireless to wired CarPlay dongles.
There is wireless CarPlay now. But it does have higher latency.
