I came across a new fiesta on an unlit dual carriageway one night when it was absolutely pissing it down. Tried to let him know at a roundabout but he either didnt hear what I was shouting when beeping got him to put his window down or thought i was wrong and sped off. It was really hard to see the car from the rear in the conditions. If someone's beeping at you at night then checking the obvious should be second nature, if he didnt know then that probably means he always drives without them on. Some useless tw*ts out there.
