GNCAP ratings and the methodology are quite transparent for all to see.
They have a PDF detailing what testing they do:
https://www.globalncap.org/s/assessm...Adult-d87a.pdf
They have videos and photos of the results, and a result PDF describing their analysis.
What further explanation do you want?
These "controlled tests" are designed to mimic real world scenarios, based on the statistics collected about road accidents.
They aren't lab tests in that sense. They do actually fire a car at 64kmph straight at a barrier.
That is among the most common type of accident I can imagine.
If you think 64kmph is too low, again, that is a very baseline speed on most roads.
This does not mean that a 5 star car is going to suddenly become a tin can above 64kmph.
It takes a lot of design engineering to make sure that even at 64kmph the occupants suffer a very light impact.
However, cars that can't even manage to do that in a lab tests, are 100% a tin can. No two ways about it.
The whole point of GNCAP is to see if the car is designed in such a way, and with such materials, that it will dissipate the energy of the impact without transferring it to the occupants. If a car is made with poor materials, and is light weight (And not made of carbon fibre/titanium), it is definitely going to transfer impact to the occupants.
Also the core methodology is the same even for Euro NCAP, Australia NCAP, South American NCAP, and so on. So it is a tried and tested benchmark. Not some random theoretical test someone has cooked up.
Next up, we have MoRTH report on road accidents:
https://morth.nic.in/sites/default/f...022_30_Oct.pdf
This clearly outlines that being hit from the back, and head-on collisions are the most common types of road accidents in India.
Meaning, GNCAP tests do cover the most common scenarios.

A 5 star rated car will definitely be safe even at 100kmph. Your assumption that the rating is worthless at that speeds is wrong.
There are multiple incidents highlighting these things.

Quote from the above team-bhp article: "Seconds later, a truck came and hit the backside of my car. We were not hurt as both of us were wearing seat belts and thanks to the build quality of the car, we felt nothing more than a bump but the backside of the car was damaged. Both the truck driver and the biker ran away from the spot."

I'm picking Nexon because you mentioned Nexon. You can literally just Google any 5 star rated car + accident, and you'll see report upon report of how these cars have saved their occupants even in the most dire of conditions.
In fact,
https://www.cartoq.com/mahindra-xuv7...s-on-it-video/
This is a testament to just how a 5 star rated car can save its occupants wayyyy outside the tested scenarios. A loaded truck container fell on top of a 700, and the structure held up for long enough that all occupants could escape unhurt. Not just that. This car was later driven to the service center. It was fully functional after taking an entire container.

This, I agree with. This is why my dashboard is completely clear except for one anti-skid mat. Which I never actually use even.

And Indian manufacturers are infamous for their quality control, and we all are witness to that. If Tatas and Mahindras have visible niggles from day 1 like infotainment, camera, software, and various electronics - and mind it, these are the things that we can SEE; who's to say that the components you CAN NOT see are performing at their optimal?

Quality control issues can happen with any manufacturer. No manufacturer has been free of blame. Why are you singling out "Indian manufacturers"? Step outside of the realm of shorts and reels, and you'll see a different picture.

JD Power. An independent surveyor. They have run surveys on initial quality, i.e. complaints/failures in the first 6 months of ownership.
Their analysis? "More than one-third (35%) of the problems cited are in the categories of audio/communication/entertainment/ navigation and features/controls/displays." Meaning most issues these days are cosmetic.
Apart from this, Tata Tiago, Tigor, and Punch have shown up here in both years. Meaning, they had among the least amount of issues.
Also talking about failures,
What if a Taigun DSG seized at 120kmph? Those DSGs are notorious for failing!
What if your i20 starts to free wheel?
https://www.team-bhp.com/forum/india...-response.html (Hyundai India - The occasional serious quality lapse and apathetic manufacturer response!)
If it is a given that all manufacturers are prone to quality issues, isn't it a safer bet to use a car that is built safer?

First off, the base chassis and panels of each and every vehicle are welded/assembled by robots. So they are exactly the same with some deviation in 99% of the cases. Chassis and panels is what mainly contributes to the 5 stars, and there is not quality check for that.
What are they supposed to do, crash test every manufactured chassis? And this applies to all manufacturers. Not just "Indian manufacturers".
About the airbag "incident", this has happened to literally every vehicle you can imagine.
Feel free to go through:
https://www.team-bhp.com/forum/road-...eploy-why.html (Frontal Crash - Airbags didn't deploy. Why?)
At the end of the day, it's an electronic component,
manufactured by a third party.
Have you seen the number of recalls that have happened over airbags? I have! Here are some:
https://www.hondacarindia.com/press-...ators-in-india https://www.volkswagen.co.in/en/owne...-campaign.html https://www.team-bhp.com/news/skoda-...takata-airbags https://www.landrover.in/ownership/a...all/index.html https://www.reuters.com/business/aut...es-2023-01-18/
This is among the most common issue, and lies outside of the purview of the manufacturer.
Again, you CANNOT QC assembled airbags. Airbags are a one and done mechanism. So manufacturer has no choice but to rely on the third party vendors certifying their airbags.
I hope this broadens your view on the whole situation.
Sorry for the HUMONGOUS rant, but I am extremely pedantic about GNCAP and build quality being taken lightly.
