Saw Something Interesting Today

Today, while out walking to get some exercise, I noticed something. On a newer Ford full-size passenger van the wheels had seven lugnuts. At first I thought I was seeing wrong and counted several times and then further into my walk saw another van with the same kind of wheels. Now in the past I have seen vehicles with 3 lug wheels and 4, 5, 6, and 8 lug wheels. This was the first that I noticed a vehicle with 7 lug wheels. I remember laughing in Driver Ed class at the illustration of a wheel with 7 lugnuts in our Driver Ed book. Turns out whoever drew that picture was way ahead of the times.
