Yes, it's possible, as soon as
1. We have access to all our media (including, for example, things we've performed and recorded ourselves) through a cloud service supported by the Tesla media player, instead of the current offering which only gives us access to whatever they happen to have in their licensed collections.
2. We have wireless data coverage without any interruption anywhere we can drive our cars, including the back of beyond, mountains, subbasements, etc.
Until then, I'm betting on the dodo. Item two, in particular, seems a tall order.
