From a post with "Tesla spyware" as title I would expect more than literally two sentences that say "[...] my Model X was uploading ~2.6gb of something to Tesla when it parked and connected to WiFi. Hopefully turning all these settings off stops it"
I thought the sentry data was collected and the data collected when driving on roads etc was collected for training purposes. Would that be 2.6gib worth of data? If it includes video from all the sensors and cameras I think 2.6GiB is still a small amount.
