The problem is that we have heard lots of things about changes wich will improve overtaking, and not many of them have come forward. Some because were totally wrong, some others because of politics, who knows. Reducing aero efficiency is a good start, but having engines frozen is a great step backwards because this way youīll maybe save costs but at the same time you are dooming a team (for good or bad) to stay in their position some more years because they canīt improve their engine or the others canīt do the same with theirs. I know engine freezing is not the point of this thread, but IMO this solution will not bring F1 to a new world unless they think seriously about their own rules.
