> Try mentally taking apart a car. Can you point to the component that supplies the transportation functionality?

Transportation, in agile terms, isn't a feature or primary function – it's an epic. I agree with the conclusion that emergent behaviors cannot be well implemented solely as features, but it's also somewhat tautological, and the argument can only be constructed from the initial (invalid) premise.

Transportation is a set of requirements about getting from point A to point B, with various conditions.

We can easily identify requirements that are implemented in a car which are not Transportation requirements.
