May be relevant: noticed a new car dealer today, entered to inquire. Full "gadgety" monsters, pointless bothersome tech just for any-tech thirsty customers.
Salesman told me that it does not work without a smartphone.
And that it requires the dealer - the vehicle is a still statue without a whole infrastructure behind it to let it work (must be network connected and exchanging with some servers in China, he said - I do not know to which extent; the company greenlights the links to your other gear, and without that the car will not work... Things like that).
