Pretty much nothing would have saved that car from flipping in that particular situation!

Let's analyze carefully the dynamics. The car gets hit in the rear left corner. The result is completely blown rear tire! That makes the car "sit" on the ground with the rear left corner. While the car is sitting on its rear left corner, is also spinning towards the left. So now we have a "rocker effect" which means the sitting low left corner results in elevating higher the front right corner. The car is already sidewise, with its right front "up" and its rear left "down" (sitting on the floor). That is a fantastic scenario of more air coming "in" and no air going "out".... at that point nothing can help as the situation only escalates, rapidly.

If that car remained on its four tires and the floor was parallel to the ground at all time, the flip would not have happened, and that is what the vertical fin was introduced for.
