That's not even accessing Tesla's data. That's just accessing the airbag system's event data recorder, which is a US-mandated device in the airbag controller, not a Tesla thing.
Airbag controllers have a circular buffer of the last 15 seconds or so of the vehicle basics - speed, steering angle, acceleration, braking. No GPS. That data can usually be retrieved from the wreckage after a crash. This requires physical access to the vehicle. The data is used to analyze airbag failures, especially unwanted airbag deployments, and for crash reconstruction.
Airbag controller data is much less extensive than what Tesla seems to sending back to the mothership.
