To paralyse a Formula 1 team with fear, put those in charge into a position where they must impose team orders. The result will be ham-fisted attempts to look like no team orders exist, followed by all sorts of verbal contortions and semantic arguments as they try to convince the rest of the world that something that very obviously happened did not.
Why? Because team orders at their mildest are unavoidable and at their most extreme are blindingly obvious. It's part of motorsport, and F1's regulations actively encourage it. To name but one rule, each team has a single pit box so that inevitably means there are times where you must favour one driver over the other with stop timing.
Different drivers have different balance preferences and often a team will have to choose one development path or another that might favour or hinder one of its drivers. As we saw at Monza, even the decision of which driver goes out ahead of the other in qualifying can lead to accusations of favouritism.
