Increased data usage from CarPlay radio streaming

While being able to stream iTunes radio, Spotify etc. using CarPlay is cool, it will use a lot of data obviously. How do you think people will deal with this in this age of data caps? Do you see a time when streaming services will offer to pay cell phone providers for the data used by their apps to keep customers using their service? I still kick myself everyday for giving up my unlimited data on ATT to save 5 bucks a month back in 2009. Obviously I had no vision of how cell phones will transform our everyday lives and how much data can be consumed by the various apps.
