Funny!.The US has 1340 filling stations and only 146,000 approx cars on cng, while India has 331 filling stations and approx 334,000 vehicles on cng!.Thank God only buses and autorickshaws are mandated to ply on cng!.I feel for the car buyer in Pak , having to chug along with a live cylinder in his trunk.What a price to pay!.I'm ANTI CNG and proud to say so.
