its all about life cycle management, the bit no one cares about in a project.
This is classic IT project management where the user experience for signing up is simple and integrated and seemingly all one thing, the user experience for unregistering is fractured go to 10 different websites to unregister everything and by the way we won't tell where to go you have to guess.
If Mazda offer teh ability to sign up in car it shoudl take responsibility of end of life and at least notify you that you need to deregister or better still allow you to do it in car. Yes TomTom messed up but Mazda need to step and manage the whole process end to end not just the bits it wants to do.
Biting the hand that feeds IT
