You can see the curb rashed up and the pretty improvised fix to the sign from a previous accident I suppose, since the map says March, 2021.
Using invisible-to-humans paint on signs for adversarial recognition attacks on autonomous driving systems would also be an anti-Tesla tactic not entirely unreasonable to consider.
"Tesla autopilot crashes right outside Tesla factory!" would be a desired headline for a certain crowd.
It'll be interesting to see what caused this, at any rate, probably less than 1% chance the above is what happened.

The pole at the end of the divider with the sign facing away, stretched-arrow street paint left-turn symbol, and the enormous expanse of intersection pavement are all a little disorienting.
