Regarding the lapped cars
One thing I hadn't realized about the lapped cars, is that the only reason they were between Hamilton and Max was because Max stopped for new tires. Max had cleared all of these cars before the safety car incident. At least that is the impression I got from Joe Saward's article on the race. (I can't re-watch to confirm, and I am not sure the ESPN coverage would have answered this question anyway.)
If this is the case, that might explain Masi's initial plan to leave the lapped cars in place, against the standard practice of allowing them to unlap themselves.
I still think that leaving those cars in their position between Hamilton and Max would have made a more satisfying conclusion to the ending.
