*YOU* can't!  *I* can!  I have a button on the dash that connects me to
the house via a "long range (1/2 mile) cordless phone".  So, I can talk
TO THE HOUSE (not to her) and tell *it* that I am on the way home -- adjust
the HVAC, lighting and entertainment, accordingly.  If I've been out
shopping, maybe tell SWMBO (for me) that I am on my way and would appreciate
some help unloading the car.  Open the garage door BEFORE I get to the house
and have to wait for it to completely open.

You have very clever houses in your area.
I prefer to adjust the lighting when I'm at home, not from half a mile away.

Most modern cars "talk" to their makers.

 So you keep saying but you never specify how.
GPS is down only (no return path) so my car is not using GPS to talk to anyone but it could obviously send its location by other
means.
WiFi almost always needs a password or a captive portal agreement
but when the car is in for service it would be possible for the service location to connect it to WiFi.
Bluetooth is short range so it isn't talking to the makers.
That leaves cell tower communication.
 If my car is using cell tower access to talk to its maker without me knowing then I want to know about that.
Some cars do use cell tower communication, for example leased vehicles where the leasing company wants to track the car,
but that would be in the leasing contract and only works where there are cell towers.
 Which if the above methods is the car using to talk to its maker?
And when is it using that method? On the move or in service or at home or other?
Does the car store information about my use of the car for later transmission to its maker?

<...>
Many modern cars have cellular capability that is not exposed to the user and just used for telemetry etc.
Often it is not used for software updates, that requires a wifi connection.
I assume the car manufacturer has some form of limited data transfer agreement with the cellular carrier.
There is usually no monthly charge to the car owner for the basic serivce, it is covered by the manufacturer. If there are additional capability that also exploits the cellular link there may be a charge for that. For example on the Tesla there is a $10/month charge if you want audio streaming, real-time traffic information or improved map capabilities.
