It was a long time ago and I cannot bring them back at will, sadly. However, one lady was looking at a new car and it was at the intoduction of two speed wipers ( there is a clue as to how long ago) and she looked at the stalk which had the numbers 1 and 2 on it. She asked what it was and I said the wipers. She said "how clever is that? You don't need both wipers on if there is only you in the car do you?" I agreed with her of course, as a good salesman should.
