Here’s an interesting tidbit Tesla hacker greentheonly found while digging through the 2019.40 firmware:

While looking through the symbols in the firmware, Green apparently saw some code or configuration keys referencing “CityStreetsBehavior”, which he claims was not there before.

This would suggest that work is being done to enable city streets functionality for Navigate on Autopilot, which would make a “feature-complete” state for Tesla Autopilot.

We’ll have more news on the rollout of this functionality as the story develops.
