The gas station attendant refills Manns car and mentions that it needs a new radiator hose, but Mann refuses the repair.Back on the road, the truck, which has passed the gas station and continued on, blocks Manns path each time he attempts to pass. After antagonising Mann for some time, the unseen driver waves him past indicating it is safe to overtake, but when Mann attempts to pass he almost strikes an oncoming vehicle. Realising the truck driver was trying to trick him into a fatal collision, Mann passes the truck again, using an unpaved turnout next to the highway. ........
