Revealing mistake: When the team attends Han's funeral, Deckard Shaw is watching the team in a Maserati Ghibli with tinted windows. When Dom notices him he then chases Shaw in his muscle car. During the chase the Maserati Ghibli is seen twice with clear windows with a man in a mask behind the wheel. When Dom and Deckard come face to face with the cars and then crash into each other, the Maserati Ghibli is then seen again with clear windows. After the crash when Kurt Russel makes his entrance the crashed Maserati Ghibli still has clear windows.
