Tesla recently rolled out an option to enable a 'chime' when the light you're waiting at turns green (regardless of whether AP is on).
The traffic light renderings were always so crude that I often wondered whether the car understood which lane was controlled by which light. But since enabling the chime, I've been pleasantly surprised. When sitting in the left turn lane of a multi-lane road, the green arrow turned green (while the other lanes remained red) and the car chimed to let me know my lane could proceed. Same thing when I was sitting at a light waiting to turn right (this particular intersection has a dedicated light for right turns).
It's a small thing, but I found it encouraging.
