> The cars don't support Carplay, so I had to figure out how to log into some app on a touch screen. Eventually, after much frustration, I could get bluetooth to work so it could function like a car head unit from 2007.
Coming from a place of genuine curiosity, why would you prefer CarPlay over logging in on "some app"?
I currently have two cars with CarPlay and a Tesla and I _personally_ find the Tesla infotainment system works better than CarPlay (probably because of the integration).
On the other hand, I can imagine on a rental car it'd be easier to just plug your phone in via USB and have all your apps & whatever on your phone ready to go. I guess CarPlay is better if you switch cars a lot and (potentially?) the Tesla system is better if you have the same car all/most of the time?
For a counter anecdote - my tesla went in for some minor service the other day and they gave me a loaner, the loaner worked exactly like my personal car, logged into all my apps and whatever, seat, mirror temperature, drive mode etc all synchronized. I wonder if more people owned Teslas as their personal vehicles switching to another Tesla would feel more normal?
