Every feature on the car will be a subscription... Heated Seats, Fast Charging, Nav, everything
Of course they will be "free" for the first 3-5 years of ownership, the free is non-transferable to a new owner... and you will be able to get the GM+ All Access Plan to "unlock your car's full potential for only $500 a year".....
This is not a GM thing, this is the dream of all Auto Makers..
You may "buy" the car, but you are not "buying" the software that runs the car...
