Driving back from Fort Augustus to the Midlands today I noticed a very curious phenomenon. It seems all the cars I saw are driven by sheep content to play follow the leader. Coming over Rannoch Moor I had the misfortune to find myself at the rear of a queue of around 20 cars and 3 HGVs all doing 40mph (speed limit was 60). Two of the HGVs were at the head of the queue and clearly the cause of the delay. In spite of there being several long straights with no oncoming traffic not one of the cars further up the queue even looked like trying to overtake. Over the next 10 miles or so (and no doubt accompanied by much tutting and shaking of heads) I finally managed to pass the entire queue. Not one other car followed my lead - all were content to just sit there in the queue doing 40mph playing follow the leader. Not once during any overtake was there a dodgy moment nor did I exceed 60! The two HGVs at the head of the queue had a sensible gap between them too. I subsequently saw exactly the same driving behaviour just out of Tyndrum. No one prepared to overtake a slow moving vehicle. I'm almost certain that either sheep have learned to drive or we have entered the age of robot automaton drivers.
