I think the biggest contributor to the spectacle has been computers. The amount of AI processing now, and before that, computationally derived simulations means that all strategies converge on an optimum approach even before the compound hits the circuit - the cars are relatively dialled in prior to arrival and are only tweaked (assuming correlation has been achieved). Before this, sometime around the mid-2000s it was done by driver feel and could produce wildly different performance of the course of the race from teammates let alone teams.
If I could do one thing, that would be it to start with and let the drivers/mechanics/strategists 'feel' their way through the practice sessions.
