Petrol station are still there and they are legal. Only the public transport like the government run buses and the private taxis/auto rickshaws are those required to run on CNG. And I would venture to say that 100% of them do, mainly because it is less than half the cost of petrol. In fact, a number of car owners are moving to CNG too for the same reason.
