I don't know if it does or doesn't, but perhaps all the rebar in the concrete is like being in a Faraday cage.Yeah, if a compass didn't work down there, we'd have bigger problems than no nav.

I question your statement that a compass would not work in an underground garage. Have you tried? The earth's magnetic field should have no problem penetrating 5 levels underground. After all, it does originate in the earth's iron core does it not?

Compasses still work in Faraday cages. (GPS and cellular signals, not so much)
About the only thing that stops a compass working is another magnetic field. (not saying that couldn't exist there, but unlikely enough of one to knock out a compass throughout the entire structure, more likely only in one corner of it or such)

Things you may not have discovered about your Model S... the pedal spacing is very accommodating!

Sorry if mentioned earlier...
I just found that when using TACC and in hold mode in traffic, one does not need to tap the go pedal to start moving. Just pull the cruise stalk toward you and off you go. Minor, but what the heck.
Another I have found is that if I am in cruise and I hit a sharp corner, the car will wait until I am through the corner to accelerate up to the set point. Now that one I find pretty neat.

If you get out of the car while still in D, it will automatically shift to P.
Of course I wouldn't be so absent minded to try that ..!

Actually it is very embarrassing for me but it happened to me a few times... It's probably bad for parking brakes to move to P position without foot brakes, so I should never have done that.

It'll do that too if you unbuckle your seatbelt and lift your butt going through a car wash. Trust me :redface:

Mine was super embarrassing. i had a loaner the week and noticed that the AC blower went up to 11 and mine only went up to 8. Upon bringing the loaner back to the SC I asked about the difference. Come to find out i have had mine in range mode since delivery 2 months ago and this reduces blower output to 8.

I don't think the Model S has a compass anyway. For example, if you back into a parking space, the arrow on the map representing the car rotates in the direction of movement rather than "backing up" on the map, which suggests it is using the differential of GPS locations to determine the arrow's direction. I'm not sure how it's correctly registering your location below ground though, without getting a GPS signal. Maybe there's some sort of compass or gyro that it falls back to only when GPS fails?

I was trying to open the charge port on the wrong side the other day. Really frustrated that it wouldn't work.

Unless I'm missing something, I kinda think it does have a compass. I back into my garage at home and if I look at the map in the app on my phone, it always shows my car pointing the right direction rather than the direction it was last traveling. Then again, it might just be flipping the direction 180 since it would have known I was last in reverse.

I think it'd be helpful here to define what you mean by "pointing the right direction". Not arguing with you, just that we might have a different expectation. I would say that for the direction to be correct (or "right") would mean that the arrow depicts the orientation of the car, and always faces the same direction the car is. So if I back into my garage, I would expect the arrow to point in the direction of the garage door, not the back of the garage. In my experience, the Model S shows the arrow in the opposite direction, as though I had pulled forward into the garage. This could also be considered "right" however, as it represents the relative direction of travel. It is this behavior that leads me to believe there is not a compass, because if it knew the direction the car was facing, it could keep the arrow in sync with that direction. It could also just be that they chose to depict the direction of movement though, regardless of the orientation of the car.
Also, don't get me wrong, I don't really mind the way it works now. I'm not suggesting they add a compass just so that the arrow can be shown to "back up" when in reverse. I think it's just an inherent limitation of the method they (and other nav systems) have chosen to depict direction.

Well...
As an aside I thought it was interesting that the only controls that changed orientation were the buttons for the glovebox/hazards. Everything else is just moved over with the layout intact-- even the VIN is still on the right side. The ergonomics of having all the display menus on the far side of the screen are a nice penalty for our former overlords.
(Cheers from the colonies, gents).
I thought I defined it pretty well in my post when I said "it always shows my car pointing the right direction rather than the direction it was last traveling". The behavior you're describing is the exact opposite of what I've experienced.

People seem to think all the controls in British cars are reversed because the gear selector is now on your left, when in actuality, that's really the only major thing that changes. All the steering wheel controls (blinkers, wipers, etc.) and pedals are in the exact same orientation, just on the opposite side of the car.
