Power Braking – What is it for, is it bad for your car?

Question

Is there a scenario where a layman would use it (i.e. evasive maneuvers)? In what scenario would a racer use it?

Edit: Yes, I mean accel+brake. Heel-toe, etc

In: Engineering

Answer 1

Someone trained to drive a car with evasive techniques (i.e., a Secret Service driver) might use this, but I can’t think of much else outside of a race track.
