the key point to remember is quite how VSA or ESP or TC or whatever else it gets called, works.
The starting point of the whole process is when one wheel starts to rotate significantly faster than the other wheel on the same axle.
It has to be significantly faster to allow for the normal differences due to just going round a corner.
Quite how fast the VSA kicks in then is dependant upon the number of sensors per wheel (at extremes, 1 sensor per wheel needs at least 2 full rotations to recognise the difference, 1000 sensor react more quickly), and then any built in delay whilst the software decides what to do about it.
This is all combined with a shed load of other data - yaw and pitch, acceleration, position of steering wheel etc etc etc
