Ice road trucking, where the surface decides your speed. Thick ice holds anything; dark ice laced with glowing cracks will not take a loaded truck at pace, and the only way to find out is the sound it makes under you. Jobs come off a board — mining supplies, a fuel tanker that keeps sloshing after you brake, long pipe bundles that swing on corners, explosives that do not forgive a pothole. Arctic Truck Driver is slow on purpose, and the tension comes entirely from how badly you want to hurry.
