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

On turbo cars I’ve heard this referred to as “brake boosting” the idea is that the turbos need exhaust gas to spool up and create boost and depending on the size of the turbo boost can come on at different rpm levels. If you don’t start creating boost until 3500 rpm you would apply gas and brakes until you were at 3500 rpm or greater that way when you let go of the brakes to go your car is already in its boost threshold making better power. Are there scenarios where a layman would use it? Sure want to be a jackass and launch as fast as you can from a red light? practically there’s no good reason to do it and it’s definitely not good for your vehicle but boy can it be fun. I don’t really think there is a good reason to do it in most naturally aspirated cars except maybe stop light on a real steep hill and you don’t want to roll back slowly let off the brake while you’re accelerating but I think that’s a whole different thing than what you’re asking.
