Last year @daringfireball wondered about CarPlay demand in car rentals (https://daringfireball.net/2023/04/gm_carplay_iphones#fn2-2023-04-10)

This week I rented a 2023 GMC Tahoe “with builtin Google” and it is a shitshow. It…
* throws errors about Google Voice Services once a minute
* crashes into a “Restarting” screen every two to three minutes
* CarPlay dies with it, which then takes out navigation and causes missed directions
* this also stops music, from any input source

I will never rent another GM vehicle.
