Derating

hey there

Is it a bug or is it normal that the cars never derate ? I mean, i'm spending all my races pressing the same button which is the selector for ERS deployment, from None, to medium (which is useless btw) to Chrono to overtake.

On F1 24 cars stopped using battery when we were in 8th gear (well there was a bug with the rechage tho but at least all the battery weren't away after two laps) 

On F1 25 even the medium mode is pumping 7 to 15% a lap depending on the track (which is a joke)
Spending my whole racing dealing with 1 button is kind of annoying....
