Depends on the market. In Australia Tesla is much pricier than all the Chinese options (more the norm). In my area people who would have probably bought a Tesla are looking at BMW's range.
They have some rider rules around keeping the car clean (screenshot link below). I'm not sure if they are enforced to this level but they do have at least one camera in the car (above the middle rear seat).
I like this theory. I wonder the "Delete after 30 days" part used to work and then they added some more security features which made it not work unless the phone was unlocked. i.e. it could delete out of the DB but failed to delete the file if the phone was locked when the job ran.
