Honda had a Civic GX CNG model in the 2000s. Home fueling was possible with a fueling device, though refill times were on the scale of L1 or L2 charging. A number of transit authorities ran CNG buses in the 1990s, but reliability and tolerance to hot weather was an issue. Toronto ended up re-engining a number of its CNG buses with diesel. Not all places have NG infrastructure, and many parts of North America are extremely rural. In summary, reliability and overhead cost of building out pipelines for not much gain are the issue.
