It’s pretty easy to clear out a collapsed tunnel compared to completely rebuilding an underground facility full of high tech equipment.

I have a nephew that worked at Tesla as a software engineer for a couple years (he left about a year ago). I gave him the VIN to my Tesla and the amount of data he shared with me was crazy. He warned me that one of my brake lights was regularly logging errors. If their telemetry includes that sort of information then clearly they are logging a LOT of data.
