Vehicles have been considered the one area where owners have a right to repair, but manufacturers haven't given up, and after a Massachusetts law attempted to bring right-to-repair up-to-date, Subaru and Kia turned off options like remote start on new vehicles for buyers in Massachusetts.
One buyer said he would have chosen a Toyota had he known that ahead of time and the salesman asked "Do you have a friend whose address you can use in Rhode Island?"
To fulfill the law every manufacturer would need to make dozens of gigabytes of data generated every hour by every new vehicle accessible to the owner and aftermarket shops, which was a bigger issue than anyone realized.
Someone estimated that data was worth $92B.
