Driver's weight

It's not inactive, at least now driver mistaken was removed we could notice that its effect is very small if you compare with fuel weight.

I've run a test with two drivers that were supposed to do same times (L Thomas against R Hamilton in a friend's account). With a 10kg difference there was only 1 race of 13 that heavier driver (Thomas) came ahead Hamilton in qualifying.

When he came ahead, gap was 0.137s (https://igpmanager.com/app/d=result&id=28774397&tab=qualifying)

When he was behind, gap was usually close:
5 races Thomas came behind only 0.010s or less;
2 races Thomas came behind between 0.020~0.011s;
4 races Thomas came behind between 0.125~0.021s;
1 race Thomas came behind more than that (max gap was 0.279) https://igpmanager.com/app/d=result&id=28774394&tab=qualifying.

After 13th race, I trained weight and qualifying times started to be exactly the same until the end of that season.

As per race pace, I don't see any difference by having a heavier driver in your team.

So, As you correct recommended, I think everyone should train this skill to minimum of each gender.
