Audi “Tailwind” (00:50)# A country lane in the middle of nowhere. We see an old rusty truck turning from a side street into the main road. Everything seems pretty normal… until the vehicle reaches speeds quite unthinkable for this type of truck. Even the farmer’s agricultural colleagues can’t believe their eyes. Disappointment only sets in when it turns out that the high speed was caused by the slipstream of an Audi S4 the truck was following.
