Zooker - following on from the comments of everyone here I was thinking about how I could see the same result again last night as I was driving, and I had EXACTLY the same thought as you have suggested. That is uncanny! I think it would also serve to reassure my fellow pasenger who was convinced we had experienced a near miss. Suggestion of a pint afterwards is a great idea too
EDIT: I don't even need to buy a copy of the said "Sheet 129" - I have one right here!
