Something to keep in mind is the Attach Mode gives the cars more power, but they are using extra battery for it. It's not free horsepower. If implemented in RR3, you would have to be conservative work your power usage.

Regarding F1, I think it's similar to the KERS. It's like a hybrid battery that gives them extra power when they want it. LaFerrari's hybrid system is similar.
