fwd cars are simply put inefficient accelerators. when accelerating the weight of the car goes towards the rear thus leading to loss of grip in front which presents itself as wheelspin.

likewise how brake bias put towards the front is more efficient than a more evenlu split brake bias, the weight of the car goes towards the front while braking

the danger of lift-off oversteer is overstated. At lower speeds it is not much of a risk based on how hard you are both braking and turning. While at higher speeds it is more dangerous because it is easier to do.

The reason why lift off oversteer is so dangerous is because it happens during turns that people enter too fastly so they instinctively step on the brake while turning

lift off oversteer isnt common while braking in a straight line because on the longitudinal axis is the tire grip at its surest

likewise is the tire grip at its surest when it is on the latitudinal axis on turning

with this in mind you can deduce that tire grip is at its weakest in the diagonals of these longitude and latitude axises
