We can use your terminology instead. The terms make no difference. The
point remains the same: building roads can create, rather than reduce
congestion.
You have only to ask anyone who has lived on a small road which suddenly
becomes the endpoint of a new major road, and becomes congested, when it
wasn't before.
I'm perfectly happy to call all of that congestion "previously unmet
demand." It's still congestion, at a place where it didn't exist
before. I'm not making any value judgement about whether that
congestion is "good" or "bad". I'm just talking about measuring the
amount, something that we can do objectively without having to make any
value judgements.
