The Impetus perk reduces base cost of sanity when traveling from 5 to 4. It shouldn't be confused with decreasing cost of moving through specific terrain or tiles, but the whole trip itself from A to B. Thus the profit of this perk is extremely marginal, unless the expedition is going to constantly stop and initiate new journeys.
Useful for reducing movment costs if you are not taking any view distance increases or not buying any map awareness equipment (coston flares, weather balloons etc) and thus have shorter and more frequent trips.
Tips EditIf you plan on saving on equipment cost or other travel perks, this one can actually be quite handy, since your trips will be shorter and you will have more of them, thus maximizing the effect of the 2 point reduction per trip.
