Let's not get off the topic here. It makes no sense to compare cars and soft-drinks, especially since there are more 4 wheelers than 3 wheelers in India, number-wise and brand-wise.
The topic is pesticides in soft-drinks. Whether they were in the water that these companies used or otherwise, obviously coke and pepsi have a different standard for their consumers in the west and their consumers in India. I see nothing wrong in the ban. When i buy a coke, I pay to drink a "COCA COLA", the same as you would in the US, if it is not the same, then either they shouldn't be selling it as such and if its dangerous to my health, they had better not be selling it at all.
But, seriously, I think you may misunderstand how the Coca-Cola company operates.
Coca-Cola sells its syrup only, to local bottlers. It is not Coca-Cola that prepares and bottles the product; the local bottling company acting under license mixes the syrup with carbonated water and bottles it.
If the local bottlers are in fact using contaminated water, Coca-Cola will be the first to yank their license. IF this is a true accusation and not an attempt by local soft drink manufacturers to corner the market.
That's nonsense. Coke and Pepsi will not allow their bottlers to hurt their brand. If what this article claims is true, then these two manufacturers will be all over this. A company doesn't create the most recognized brand in the world by treating their customers in the manner you describe.
