Weight shift occurs due to torque on driven wheels. Wheels spinning put limited torque relative to limited (dynamic) slip of spinning wheels. With weight shifted rear it should be easier to lock fronts for a moment. I cant imagine iRacing have it all wrong.
Although it should momentarily shift weight to front (as torque around rear axis is neutralized by torque around front axis), creating bigger braking force.
But with very light and stiff front, big front brake bias, big braking force and ability to spin rear wheels - it can be possible. I have buggy with 90% mass on rear. At some circumstances (slippy dirt) it can be very understeery under heavy braking and rear wheels spin. I had to make front as grippy as possible (tires, soft springs) to balance it.
I lived under communist rule. Luckily, they didnt send at this time to lagers to teach you that but had much subtle ways. Bah, the methods didnt really changed.
"You are not special" - individualistic equality?
I know translation of that slogan from more harsh (totalitarian) environment: "Your life means nothing and can be replaced or wasted". Beware.
I dont know a mobile phone or even smartest smartphone with such receiver - thus it has to localize itself and gather data from servers to compare its position and planes around.
I thought it compares GPS data in your phone with actual planes positions given that planes in air rarely go in distance closer than couple of kilometers.
