Yeah, it is definitely really nice if you care about privacy/security and can live with some minor limitations. I just switched back to stock Android from GrapheneOS though, to get Android Auto working. My car's built-in navigation just isn't good enough any more.

Yeah, that is annoying that Android Auto requires such permissions.
OTOH, I have used it twice in two models of car, and in both instances it would stop working until I unplugged and replugged the phone. I just keep the phone visible in the cup holder now.
