If I buy a car containing eg. heated seats, but the feature is disabled, because I didnt select the proper addon package, who is going to sue me, if I add a switch, and connect the heating elements to 12V supply myself? Or buy an addon controller? Or even buy addon seat heaters?
In practice, if you buy the car hypothetically containing heating seats but the feature is disabled, then the hypothetical company (that is probably Tesla) will void your warranty and refuse repairs.
Which is a great argument for Right to Repair, but makes everything a hassle on the consumer side - any future interaction with the company around the vehicle is a landmmine waiting to be triggered.
If they sold a feature, it's yours.
