Hailing the Supreme Court's directive to the Gas Authority of India Ltd (GAIL) to improve CNG supply in Delhi by September 21, the Federation of Automobile Dealers' Association (FADA) has said that the city needs an efficient fleet of vehicles. Association convener Rakesh Jain said that the long queues at CNG-dispensing stations would hopefully be reduced significantly by the next date of hearing, when the apex court is expected to give further directions on the issue.
