we wud drive on petrol, as we used to do back then. rite now, neither we can drive the cars, nor the industries are running. CNG was introduced as an "alternate" fuel. we have made it "primary" one. no CNG, less cars on roads, more gas to industries, better GDP, and u never know resultantly causing the reduction in petrol price too. we all have 2 to 3 cars parked in our garages. in gud old days, we only had one. so i hope and pray we revert back to the same days now.
