There were lots of reports that
Elon asked people to print out code and bring it to Tesla engineers for review. They’re Rumors and pretty easy to find. Wrapped up in the whirlwind of news from the last 24 hours was that LOC was a metric used. Also rumored was that Elon asked that his name not be included on any negative memo (presumably out of negative publicity?).
So no I can’t get a citation, and everything is rumors but they’re laying off 3500 people so prepare for lots of rumors floating around.
