Is there an actual source for that number at all? Intel did a marketing blog post [0] where they said 4TB per 1.5HR, but without any actual explanation of it, and since then a bunch of posts started using "per 8 hours".

I'm cautious of this number because the camera and sensor feeds are very often reduced heavily in resolution and then passed for processing, so if they are considering raw uncompressed sensor streams then that's not really representative of the theoretical stored size of the data or the size of the data actually processed.

In practice, far less data is saved. Tesla's production "Autopilot" saves and uploads 15 frames when there's an "interesting event", according to the NTSB report of a Tesla crash. (There's no imagery of the event where the vehicle plowed under a semitrailer, because Tesla's autopilot didn't detect anything that required braking before or during the crash.)
