Is it a hard requirement or is it about vendors being overzealous because it also fit their interest?
I know that the law requires some radio equipment to make it hard for users to modify so that they can't mess with some parts of the spectrum.
But for cars, the responsibility is typically of the user, that is, if you modify your car in a way that is not what the manufacturer certified, you can but you have to do by the rules or face the consequences, the manufacturer is not responsible.
But by locking down software hard, it is a way for manufacturers to make sure that they can't be held responsible and the side effect of locking down features is a nice bonus.
