they're limited by a 4G connection Are they? - they could store data to be collected in bulk when the car is in the garage for maintenance or servicing or repair. - Superchargers could include fast data transfer in their cable for cars using them. - Superchargers could include a wireless data collection from cars sopped at or near them. - Cars could connect to public wifi to upload data at any car park, any place, any time. - Tesla could have vehicles driving around, like Google mapping cars, collecting data wirelessly from nearby Teslas. I don't know if they do any of them, but none are unreasonable things for companies of 2019 to think about doing.
