I'd say the incorrect words in the title are "mandatory" and "backdoor".
This functionality is not requested and is working against the user (and it is pretty unlikely for such a feature to be done completely locally on the car, and even if it was, it will almost certain have Over-The-Air updates creating what is colloqially referred to as a backdoor.
Which part of this do you disagree with?
And it's not mandatory. It may become mandatory in several-to-many years. The law is about exploring the possibility, just like OP said. This article is Facebook garbage that somehow made it's way onto HN.
What would you propose as the definition of a backdoor that does not include the above?
