Yeah,both CarPlay and Android Auto have wireless support these days.
You can buy wireless CarPlay/Auto USB dongles for cars that only support cable.
Not all cars support that, though. Due to licensing or tech, some cars (even new ones) only support Apple car with a cable (my case). I bought a wireless adapter on Amazon and it works seamlessly.
A wireless adapter that lets you use wireless carplay on a car that doesn't have it? Could you please post a link?
I bought this one that’s arriving tomorrow. I’ll write up a review of it once I’ve used it a while.
