      Electronic stability protection.
      Basically cuts engine power to prevent wheels slipping/Spinning.
      But causes problems as seen above or in Sand, snow etc... Hence most cars have ESP off button.

      ESP does not cut engine power power; it work along with ABS system and traction control when it feels the vehicle is not "stable".

      In the above video, it will be the traction control that will work to reduce free spinning on one wheel, which also seems not to be happening as cannot see dust being kicked up from the other side (or maybe it is and it is not clear to me).

      I believe ESP will come into play only when all 4 wheels are in motion and there is a "perceived" loss of stability (wheels speeds different and also difference in traction to all 4 wheels).

      Manufacturers play around with these terms and have their own custom maps how to implement.So it becomes difficult to compare vehicle to vehicle. When driving XUV500 and Ecosport in Sand (FWD) The ESP simply does cut power. Turning it off allows vehicle to Move.

      What you are talking about is Yee-Yaw correction. Where gyroscope sensors and Steering input is checked to see if there is a "perceived" loss of stability.
      Something along those line is also called as rollover mitigation. XUV does this very well. Although its basic version compared to high end Audi Quattro (with vector correction), XUV still handles fantastic at higher speeds.

      There are very few vehicles in India with proper Traction control as you mentioned. Notable contenders being Tata HEXA AWD and New fortuner 4x4. Both of these vehicle could apply brakes on the spinning wheels (With no traction) to act sort of Fake diff locks (Brake lock Differential or BLD) allowing vehicle to move with one two wheels slightly up in the air.

      However Mahindra could not do the same with XUV. The programming is simply not replete.

      BTW- There is dust being kicked out from other side. TC is not well programmed on Crysta.

      P.s- You can see Bunny and bobby team driving XUV on Race track where he explains effects with ESP on and OFF.

      You could get the same effect by left foot braking slightly while on the gas to get a drag (braking) on the spinning wheel so that the open differential case is ruled out to some extent. A poor mans diff lock so to say. Maybe has relevance in the Crysta's case.

      Left foot braking could've been worth a try here.
      However, I am unsure if crysta will have enough torque to do so.
      Left foot braking is usually used with 4L or a torque converter to prevent clipping of engine. Because it will also drag wheels that are on the ground.

      And for a 4x2 RWD vehicle (Which I assume crysta is), engaging handbrake offers better and smoother result as footbrake anyways has more bias towards the front where braking is an unwanted effect. mild handbrake will equalize torque for rear driven wheels only.
