Grounding Kit

Grounding Kit
My question has probably been answered a few thousand times, but I can't seem to find a good reason as to WHY this needs to be done. And I don't mean the benefits (i.e. shifting, audio, mpg, hp, etc)...I mean WHY did Nissan not do this from the factory if it's as simple as four wires strung throughout the engine bay?

ground is ground is ground.
If it's grounded, adding more ground will not make it any ground[ier].
Take a multimeter and measure resistance across the various points. [should be 0 ohm]
Take the multimeter and measure voltage between the various points both when the car is off and running. [should be 0 V]
[optional] connect an oscilloscope to the various ground points and note the humms/fluctuations while driving the car (all RPMs). [should be flatline]
If the above tests are good, then the car is properly grounded.
If they are not good, replace the factory grounds as they have oxidized.
Or install a grounding kit.
to be exhaustive and if you're itching to do something:
Replace all the main factory grounds with the same length and thickness (or thicker) wire in the color of your choice
