I owned a Model Y for several years, but, at least in my city, I always felt Tesla’s navigation had pretty poor route selection during busy times of the day - like dorecting me to streets that were notoriously stop and go during rush our when the highway alternative was known to be much quicker.

Tesla is more of a technology company than a car company, that's why they managed to make a good UX.

Classic car makers are not able to make decent UIs. Plus, each car would be different. So I prefer Android Auto: it's always my Android Auto, regardless of which car I'm driving.
