It’s not lack of resources that causes FE cars to be so much slower than F3 cars it’s the batteries. F1 budgets are a tiny fraction of the R&D being spent on batteries.
If you told teams they had 200kg min for fuel, engine, motor, and battery and left the rest up to them teams would not be using motors and batteries. From a racing pov they slow the car down.
Fast cars are spectacle, slow heavy ones are not. It’s why semi truck racing ia less popular than f1.
