Too fast will kill you....
Those cars have huge downforce when going forward in the right direction. They can brake so fast into a corner which is what they have to do to keep their pace.
But, if spun backwards, you do not get aerodynamic downforce. You get aerodynamic lift. So even if your brakes are locked up there is no force onto the road to create friction.
She probably did not slow down much from the time she got spun while the other cars probably had several G’s of downforce to slow down quickly. That is why she flew by at such a speed difference.
