I am an one year X owner. Love this amazing car! Few things that bother me and should be easily fixed via software. 1) The doors control screen appeared whenever the car is at a stop which is perfect. But once placed in drive, it should disappear so I can now see the Nav, sound system, climate, etc. 2) The seat heaters/coolers should always go back to default (off) position when car is exited. Hate having to always remember to turn off all seats. Also wastes some juice if left on for empty seats.

1) Once I select D, the door screen disappears in my MX and will show the screens that I have below it. Try rebooting your screens to see if it will work properly in your MX.
2) I prefer having the seat heaters/ventilators stay in the last position. I hate cars that turn them off after every drive cycle (cough...Ford). Turning them off in non-occupied seats then would not work to pre-heat the cabin. Their electric energy use is minimal compared to other high energy consuming devices such as the heater. Also, the seat heater screen has a 'Turn off all' button.

+1 for Leli001 on both points

RE: The Boring Company
Could a version of this technology be used for long distance HVDC transmission, and the undergrounding of transmission to avoid NIMBYism, fire risk, EMF impacts, etc. An integrated grid seems necessary for a 100% renewables economy?

We are new model S owners and when I asked our dealer how the car would know who was driving if we both had our fobs with us in the car, I was told "that's a problem". Surely the car can sense there's more than one fob present so in that situation why not have a window open up showing the names associated with each fob and let us pick the driver.

lilbean | July 22, 2017

That's why I didn't program the fobs and I just select the driver profile.

burdogg | July 22, 2017

there is a simple spot marinhliss - at the top, just tap and you can select which driver, just as easy as a window opening up and selecting one :)

burdogg | July 22, 2017

To be more precise if you have not been taught this - at the top, you will see a name - whoever is the current "driver" profile. tap the name and it shows all the profiles, and you can select from there which one you want to switch to - just as easy as a window popping up.

Vawlkus | July 24, 2017

I remember reading that the first fob detected sets the profile, but I don't know if is accurate.

scabello800 | July 25, 2017

First fob detected will set the profile and that is the proper design. Having someone come into the car afterwards with another fob and therefore it pops up a screen "select drive profile" would be improper.

I think tesla owners who are considering autopilot sofware should be able to try it out for a couple weeks to see if they really want to spend the money on it rather than just watch demos online or go for a short ride with a tesla salesperson

@scabello800, what if you are the driver but your spouse enters the car first with her keyfob?
@hickcc11, that's what test drives are for

@OP, Deancwang, my door control window always goes away when I put the car in drive or reverse...it has been since day 1, since last X'mas 8+ months ago.

I have a suggestion for future models and EV vehicles in general. Rather than having to plug in and charge would it be possible to have the batteries on a removable plate so you can drive into a service station and a machine removes your battery pack (from underneath by driving over it) and replaces it with a fully charged pack. No more waiting for batteries to charge.

This also keeps service stations in business as they can handle the recharging of packs and sending back battery packs at the end of their service life for recycling.

Car owners would either pay a subscription or on demand payment with each battery swap and would mean owners wouldn't have to worry about the life expectancy of the batteries in their vehicle as they would get a different battery pack at each swap.

I assume for this to work battery technology would have stabilize and all EV companies agree on a standard.

Tesla has already prototyped that, and abandoned it as not feasible.

I’ve been sitting on this one for a while and it has the potential to lead / change / affect all electric cars in the future. First off I have a M3 reservation and have been driving a Fiat 500e for the last 3 years.

All electric cars currently have variable speed a/c systems. Most cabin heating requirements are done in mildly cold weather (30-40 degree plus). Upgrading a/c systems to heat pumps would be super cheap as all you need is some hardware about the size of your hand to change refrigerant paths on heat and software to know which heater to use. As outside air gets below around 30 degrees F depending on efficiency resistive heat would be used instead. For those who don’t know heat pumps can use 3x less energy than resistive elements! Thus on long trips where it’s 40 or 50 outside you could save 15+ miles per charge. “Huge” (hello Trump)

Further, cabin preheating could be far more efficient as heat pumps take longer to heat but do so with far less electricity. So it could be staged earlier and the heat would not be as dry as with resistive heating. To be clear we need both. But a great working system in most climates would likely cover 60-80% of heating requirements.

Finally, I’m not exactly sure how you all heat the battery, but this same system could support that as well. Again greatly reducing latent energy charges. If this system was used on the pack, it could be used all the time. With the heat pump coming on just slightly to give the pack heat at all times. In this case, it’s efficiency would likely be good down to 20 degrees or less depending on target temp for pack. Heat pumps work great at 30 degree differential even 40 but 50 and above differential they start to dramatically loose capability. But if sized for the cabin and only serving the pack, it could do wider spreads.

What do you think???

Vawlkus | October 12, 2017

My house has a heat pump. I honestly would not want one in my car, it just can’t do the job as well as the current system can. IMHO of course. YMMV.

Andersen.schuck | October 12, 2017

If you’re house had what the cars have, you’re electricity bill for the heat used would triple! I installed a dual fuel system in Massachusetts on our house there so below 25 degrees it’d be oil burner and above heat pump. In the first winter we went from from about 250 gallons of fuel to around 50-70.

All a heat pump is an air conditioner. Backwards. With outside condenser inside and inside evaporator outside. Genius.

Is there any plan to put GPS locator in the key fob?! It seems like that would be a no brainer-people lose those key fobs more than they lose their car-but you can locate the car on the phone app. Why not the my fob?

GPS locator in the key fob"

No thank you for additional Microwave radiation emissions

"GPS locator in the key fob"

GPS is passive receiver, so no emission.

But to send its location, the key fob would need (1) a cellular/wifi connection, and (2) a bigger battery :(

(1) Strap assists on entering/exiting 2nd and 3rd row seats.
(2) Brighter back-up lights. Existing lights indicate that you are in reverse but don't light the way.
(3) Option to open passenger-side door on first double-click of the key fob. Combined with the drivers-side door opening on approach option, this offers better flexibility.

How about adding adjustable suspension height similar to the old Citroen DS?
Would love to get the X, but ground clearance is too low for CO back-roads usage...

vvalentin18 | October 16, 2017

To be clear, the suggestion is for an option to maintain the high setting at speeds > 20mph

@Andersen.schuck - Yep a heat pump was suggested more than 2 years ago:
https://teslatap.com/questions/use-a-reversible-heat-pump-for-both-ac-an...

My guess is the amount of range improvement is minimal when you have a large battery like the Tesla. Heating the tiny cabin of a car takes a lot less power than heating a home with 100 times the volume.

One concern Tesla may have had is there can be conditions where the battery should be cooled, but the cabin heated (or just the opposite). The current system handles these conditions easily.

With a heat pump design, it might mean two complete HVAC systems, far from a minor expense. You might get around this with a resistive cabin heater, but then you have the expense and complexity of additional valves of the heat pump.

Interestingly, the Leaf does use a heat pump. With the much smaller battery, a resistive heater in the Leaf would consume a greater percentage of the capacity than in the Tesla. In the past, the Leaf battery longevity has been a major issue. The Leaf battery is not temperature controlled like the Tesla battery, so they don't use the HVAC system to maintain battery temperature like the Tesla.
