I've been using it this month (I own a Model 3 and do not like Musk's behaviour but don't really care, I like car), and it's been great. I have a 30-minute commute with moderate traffic and lots of lights, occasional aggressive jerks, and it's been (mostly) predictable and useful. Caveats: I don't let it make left turns in traffic, too stressful. It's sketchy around yellow lights (go through, please). It can aggressively brake for cars getting out of the road. It makes me a more relaxed, less aggressively driver, er, supervisor, and it's quirks are pretty easily mitigated by taking over the accelerator or just reclaiming control.
