It would be amazing if there was a project out there that was compatible with Android Auto but was privacy-respecting.
F-Droid
F-Droid is an installable catalogue of FOSS (Free and Open Source Software) applications for the Android platform. The client makes it easy to browse, install, and keep track of updates on your device.

if I understand correctly there is no way to make FOSS AA (protocol itself is not open unless reverse engineered). There needs to be separate implementation like AA / CarPlay and headunit needs to support it. Current best case scenario is miracast supporting headunits (but this is one directional)
The car will send completely everything to everyone anyways.
My car has Bluetooth only. I wanted Android Auto because it was awesome on my phone, so I got an Android Auto tablet off Ali Express.
It's not arrived yet, I'm expecting it after the weekend, but I can't wait to have that UI back, that ease of use while driving.
It can connect to my Car by Aux or FM radio so can be wireless. I'll be changing to connecting to it instead of my car over Bluetooth. Then I'll be able to use the UI or Voice to control my phone while it's still in my pocket.
I hope it turns out as well as it is in my mind. For £30 it's worth a go
since this is F-Droid community I didn't mention it, but I'm looking for FOSS solutions. My phone is degoogled and doesn't have android auto
Yeah I've tried that search multiple times myself and end up back on Google for driving, it's just superior
