Mr.Gupta seems to be a compulsive pessimist. As for logic, Mr. Gupta, I am sure you have come across a term known as Value. It is for the customer to decide as to what value he places on all features including quality, comfort, safety and most importantly at what price.
Yes, Tata's trucks may not be world class but why is Volvo not selling even 10% of what Tatas sell. Quality at an affordable price is what customers want and this is what only indigenous players have been able to do.
Even within quality, if you have cared to read latest JD Power findings, even Honda scores very poorly so are they third class??
Markets will evolve as the other developed countries have, when india will have a per capita income of $6000 and any one will be in a position to afford a full feature, safe car. This is an interim solution and you must applaud Tata for what they have actually been able to do.
You have only proved not many academicians prove to be good leaders(No personal offence)
