The comparison isn’t meant to be a strict one-to-one match. Many fiber companies install dark fiber mainly because excavation is costly. It’s more of a helpful metaphor than a literal equivalence. The core concept remains clear, making it easier for people to grasp the broader topic of network setup.
The road comparison doesn't quite fit well since it usually reflects raising the speed limit rather than adding lanes. In networking, people often prefer using "pipes" as a more accurate way to describe the situation.
Pipes are included in the comparison since they resemble round cables, not because it enhances the explanation of their purpose. You can knit either one to death and they ultimately serve as analogies.
