The two articles that caused such controversy in Abu Dhabi - 48.12 and 48.13 - seem clear enough in how they lay out the sequence of events in which the race can be restarted after a safety car.
But Masi still found a way to interpret them differently - and the stewards still managed to use them to retrofit an explanation for his actions in rejecting Mercedes' protest on the evening after the race.
These will need smoothing out, as will article 15.3. On the face of it gives the race director "overriding authority" over the clerk of the course in the operation of a number of aspects of the weekend, including the safety car. But in the aftermath of Abu Dhabi some have suggested that that phrase gives the race director carte blanche to do what he likes.
This is not an argument that stands up to logic, not least because it would obviate the need for any sporting regulations at all if the race director could operate on a whim. But it is one that needs eliminating from possible use.
