As I’ve said, in Scrum there is a rhythm to the work. Every iteration, or Sprint, the team tries to get a number of things done. But that “Done” implies a complete, deliverable product that can be used by a customer. If something is half done at the end of the Sprint, you’re worse off than if you hadn’t started at all. You’ve expended resources, effort, and time and gotten nothing to a deliverable state. You have a half-constructed car. It might have been better to create something smaller—something that really works.
