Lost in all this is the Force India fiasco. Two things occur to me. One is the obvious, what on earth did they do with their hub-and-nut design?
The other is their race craft: why did they bring in two cars on the same lap? Obviously Sutil's abnormally long stop made a mess of things, but separating the pit stops by a lap would have avoided that, no? Seeing the cars stacked up in the pit box reminded me of a sorry scene from a few years ago.
