One use for natural gas is to power cars, trucks, buses, and other vehicles.  Right now the majority of compressed natural gas vehicles are fleet vehicles, due to a lack of infrastructure.  At one point in the past, some infrastructure was being built out for CNG, but when gasoline prices dropped people started moving away from CNG.  Gasoline prices have again dropped, but interest in CNG doesn’t seem to be disappearing.  Businesses and governments realize that this drop in prices isn’t going to last forever.  It will probably last a few years, but there is also the potential for a sudden jump in prices if something catastrophic happened; say a war in the Middle East (who could imagine?) or a hurricane in the Gulf Coast (ditto).

Companies like Clean Energy are providing some of that infrastructure.  So far it’s only to fleet vehicles, but someday the infrastructure will expand to us, the consumers.  The sooner the better.  CNG burns cleaner than gasoline and is cheaper to boot.  If the infrastructure is built out and the cars are manufactured, it will happen.

Also, USPS is adding CNG and LNG trucks to its fleet.  The more the merrier.
