Wow! This can be quoted as an example of a "Blanket Statement". Do you have facts / figures to back your claims? Sales figures of CNG cars vis a vis their petrol counter parts? (For example : Sales break up of Wagon-R Petrol vs Wagon-R CNG) Are you aware about the CNG availability issues across the country? The Petrol only i-10 and i-20 are flying off the showrooms every month. I guess even Hyundai is dumb in this regard. Oh and so is Ford for not launching the Figo in CNG trim. And how can Toyota be so dumb for not launching a CNG Liva ? Hardly an investment to launch CNG !! Again on what basis do you say this? Have any figures? What would be the ROI of the project? Calling someone dumb is easy. Making baseless statements is even easier. I hope as informed, educated people we make more sensible statements.
