Senna and Erik Comas
I am surprised and slightly disappointed that they didn't mention anything about Senna and Erik Comas. As you know in 1992 the Erik Comas crashed badly and Senna heroically jumped off his car to save his life. When Senna crashed in Imola in 1994 Erik was the first driver to jump to Senna's help but unfortunately couldn't do anything to help him.
I'm not sure why they left this out of the movie. Unless there was a personal objection from Comes or Senna's family I think this part should have been mentioned even briefly, because it shows how wonderful of a human being (not only driver) Senna was.
