I really don't get why they have to show every car taking off from the start line. It's only interesting if the car has an issue - even then, just show a replay if something noteworthy happens.

Same with in-car shots of the driver / crew's faces. That isn't where the action is, it's just one person turning a steering wheel, and another reading a book. Again - show a replay if something actually interesting or amusing happens, no problem. But live? When has anything worth looking at happened on the face cam?
