well,Allen,I have a relative who works for Hyundai.(I hope you would consider as an expert). To produce 5 lacs vehicle a year one would require not more than 8,000 wrokers(Your estimation was wrong in the very first place).Secondly,what ancillery units are you talking about exactly?Have the Tatas cleared mentioned the details anywhere?Have they quantifiesd the number of people exactly who would be getting jobs in those industries?How much land exactly(in quantitaive terms) would they erquire for each ancillery units?
If you have these answers please clarify them first .Or else admit that you are ignorent too.
