Not quite a month, but have put in over 1300 miles so far. Here are two hardware issues (yeah, not software) of which to be aware, before your test drive:
1) The bottom of the windows is at a pretty high height. Higher than our previous Model X, for instance. This means it's harder to get a feel for what's going on around the sides of the car; for us this is mostly noticeable on our switchbacked mountain roads, but also matters in parking lots with curbs. Now, you can't see them even in the Model X, but you see more of the surroundings, so you have a better feel for where they are. Couple that with the rear-wheel steering, and the overall effect is a bit disconcerting. It's something we'll have to get used to - the boundaries of the car. The high window bottom height also extends to the dashboard, where you can't really see the front of the vehicle. The 360 camera view helps in slow speed situations, but this affects curvy mountain road driving as well.
On the test drive, we just attributed that to the feeling one always has in a new/different car. We've since adjusted our seats to be a bit higher than we would have otherwise, which helps, but only a little bit.
2) While the top of the doors is too high, the bottom of the doors is too low. Most cars are designed such that the bottom of the doors is above the chassis sill, so you see most of the sill when the doors are closed. The Gravity, however, has the door bottoms extend over the sills, so you don't see the sills when the doors are closed. This is a good look, but the downside is when you open a door, the door bottom is lower, and so is more likely to hit curbs. We just missed the first curb we parallel parked against, and so I started raising the car after parking, which was a drag.
Turns out there is a setting where you can have the car either raise or lower upon parking. So, we set it to raise, and that's been safer. Neither of us is short, so it's OK to have the car higher for entry/exit. The car lowers automatically as the speed increases, so that's all good. Dealing with those high window lines on mountain roads sounds like a total mood, honestly making me feel blind to the curbs. It’s kind of like finding the right
image editing tools to fix a shot, where you just need that one specific tweak to make everything click. Definitely keep your seat high and your wheels safe, because those switchbacks don't play.
