I finally got updates to both our Model S (2019.5.16) and Model 3 (2019.5.15) the other day, and the one feature I've been looking forward to the most is location-based auto folding mirrors. This feature lets you configure the mirrors to automatically fold when you approach a particular location and unfold when you leave, or you can configure the mirrors to fold when you open your garage with HomeLink and unfold when you close your garage. I've tried it out, and it has some issues.
We have narrow garage openings, so I always fold my mirrors before entering the garage and unfold them after backing out. I have the regular mirror auto-fold feature turned off, because otherwise my mirrors would unfold before I backed out of the garage. Folding and unfolding the mirrors in the Model S is easy, because there's a dedicated button for this on the armrest, but it's a bit of a pain in the Model 3, because you have to use the touchscreen (Quick Controls).
After I received the update (and rebooted as I usually do after updates), I configured the mirrors to automatically fold when I open the garage and unfold when I close it. You do this by editing the HomeLink settings (from the HomeLink drop-down menu), select the location (e.g., Home), and enable the auto fold mirrors checkbox (I don't recall the exact wording). I have my HomeLink set up to automatically open my garage when I approach, but I don't use the auto close feature.
The feature works great when I approach my garage -- HomeLink opens the garage and the mirrors fold -- but not so much when I leave the garage...
When I tried it in my Model S (just once), after I backed out of my garage I used HomeLink to close the door, while I was still on the driveway, but the mirrors didn't unfold. I waited a little bit and finally unfolded them using the button on the armrest. A couple of seconds later (still in the driveway) the mirrors folded again, so it seems it was a delayed response.
When I tried it in the Model 3 (a couple of times), the mirrors didn't unfold when I closed the garage, but I waited to see what would happen. I started driving up the street, and the mirrors finally opened (I was maybe 100 feet away from my house). I was only going about 10mph, so it wasn't my speed that made them open (that's suppose to happen at 31mph).
If you've tried to use this new feature, how is it working for you?
