I live in Moraga so I eat in Lafayette pretty much every weekend. Haha. Have a pre-AP Model S but considering trading it in on a Model X soon.
Cool. If you see a silver, non-pano roof Model S 85D driving around, that's very possibly me (I've seen at least one other silver S in our area, but it has a pano roof). Anyway, I can report that AP (autosteer in particular) works pretty well from one end of 24 to the other.
Bruce.
