Tesla last year started splitting data into standard and premium tiers, but it's now hinting that it might watch how much data you're using, too. Some owners have noticed a data use counter showing up on their cars with a seeming 50GB cap. It's not yet clear what this cap is for or what happens if you chew up more than 50GB of data. However, Tesla is displaying this to people with the Premium Connectivity package, not just Standard.
