I hear a lot about commercial vehicles being converted, etc. but still no real effort has been made by the automotive industry to produce CNG vehicles. Understanding that the infrastructure for CNG at every street corner is a long way off. It is the old chicken and egg story. No gas, no vehicle. Can we hook up a compressor and condensing system to our local natural gas line and provide OUR HOME VEHICLE with some CNG? So why is there just the Honda Civic?
