Yep ... Energy required scales (at least [1]) quadratically with speed, but time to target only linearly. We noticed that while commuting between two cities over the German Autobahn (A2). I could go 100 km/h and be in sync with the semis, or could go 120 km/h because at that time there are too many cars to go faster. Going slower was almost two liters gas less per day but increased travel time by only 5-10 minutes.
