I must admit I have always disliked the "every team must use two of the three chosen tyre compounds" each race meaning they have to stop at least once even if they dont need to. I woud much rather they had the old system where there would be a choice of compounds and each car could use whatever choice of tyres they wanted. If they wanted to run one set for the whole race they could, likewise they could go for softer tyres and do multipl stops if they felt that suited their car better. Different cars use their tyres in different ways, some seem to be harder of tyres than others.
To me its nonsense and ridiculous that like Sainz recently had to stop on the last lap, not because he needed to stop, but to meet the mandate of using two different compounds. In the process of that he dropped from a decents points position out of the points and as a result come the end of the season they had fallen short of Mercedes in the WCC by three points.... the points they lost by having to stop for tyres they did not need cost them the 9 million dollars bonus that would have been theirs for coming 2nd in the WCC.
I remember also earlier in the year I think it was Ocon was going long on a set of hard tyres, hoping for a late Safety Car to bank a points position, but was forced to pit from ninth on the final lap purely to meet the requirement of making a pitstop.and using two compounds.
As he peeled into the pits, the entry was blocked by photographers, marshals and other officials, getting set up for the podium ceremony, causing him to take action to avoid hitting anyone. He had to take avoiding action. No one was injured but they could have been and certainly gave him and those he nearly hit a WTF moment.
Its just a nonsense rule. They are big boys, just let them decide what tyres
they need / want out of their allocated selection, not the way the rule is.
I know this tyre rule isnt even applicable to the Sprint races where tyre choice is free and stops are not obligatory but we started talking of the tyre rule and I had to get my gripe off my chest. ( **feel better now**)
