Two scenarios.
Scenario I: A driver says a trip takes an hour. En route, there are accidents and road constructions. The journey is delayed to two hours. We are angry that time is “wasted.”
Scenario II: A driver says a trip takes three hours. En route, barely any cars are on the road. The journey is shorted to two hours. We are delighted.
Same amount of travel time, but opposite experience. All depends on expectations.
