Very true normal air goes anyday and fuel pump wala already puts lesser air in summer and slightly more in winter to maintain the temp differences and its totally impossible that u get pure nitrogen
The video was more biased towards normal air since you guys didn't include all the advantages of nitrogen such as longer tyre life , lesser air top ups , increased mileage and it doesn't cause oxidation. Although I agree that it isn't available everywhere and might be a bit costly but you have to top up your tyre 2-3 times lesser in frequency than you do with normal air plus it also prevents tyre bursts due to excessive heat.
