Even a bad idea like this has its loyal supporters who are fine with a car company making DIYers jump through hoops. Probably pay more for the luxury of not being able to do basic service on your own car.

I honestly was expected it to be lug nuts connected to the cloud that self-destructed if a code isn’t given in time. If you want people to buy your cars and take them to the dealer for servicing, then build better cars and have better service at decent prices. It’s common sense to anyone else.
