Oh wow heh. Don't think there is anything FSD or any other driver could do lol. Geezzz..
Code for potential sign looks like it might fall: (Generalizable to anything in the roadway path, I suppose)
If sign looks like it might fall:
* Notify authorities and let them know sign looks flimsy
If sign is falling:
1. slow down, inform passengers to brace for impact
2. Plot likely trajectory for sign falling
3. See if there is a maneuverable path to increase passenger safety
4. Execute best safety path, ie: swerve left, right, brake hard, accelerate, or just take it on the chin.
Execute all the above in 1 millisecond.
