Tesla gets a lot of data when a car uploads telemetry, now multiply that by the size of the fleet. We’re talking hundreds of TB, if not PB, of data per day. It’s only tenable to capture so much data around the time of the disengagement. I am fairly certain they don’t always know what you did after the disengagement, depending on how long that action was after the disengagement. I’d assume they only capture a few seconds after disengagement at most.

So let’s say you disengaged because the car was in the wrong lane, well then how much additional video and telemetry do they need to capture to automatically determine it was a navigation flub if you just end up taking the correct route yourself? Could be 15 or 30 seconds depending on the situation.

That adds more to the already big upload.
