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 the off-chance you’re referring to left-foot braking while also modulating the throttle during cornering maneuvers…
Doing this is a very advanced method of trying to balance the weight transfer of the car front to back while also separately modifying the grip of the drive and non-drive wheels via the brakes.
There’s really no scenario where a lay-person should try this because it’s likely just going to make a situation worse. Just let the electronics (ABS, TC, DSC, etc) do the hard work.
If you’re an advanced driver (many hundreds or thousands of hours on road courses), you can use this to improve your lap times on track.
Of course, race tracks don’t change much so you have time to learn a choreographed sequence of actions for each corner. Emergency/evasive maneuvers aren’t like that. You could, in theory, get good enough that your reaction times and skills might help you, but you’re better off just driving like you’re on the street and not attempting race track activities.
