Its a stupid rule and always has been because no matter how it has been worded, teams have and always will issue team orders in order to win the championship. It clearly hasn't stopped team ordersm What they need to do is split the teams during the race so they all run independent of each other. No shared pit crews, no shared equipment, no shared pit boxes. Without refuelling there is no logical justification for still having 15-18 people servicing one car from the same pit box. Let, no, force everyone run independent strategies and beat each other fair and square head to head. Mandate a starting fuel weight that is clearly more than enough to prevent fuel conservation.
