Yeah the existing infrastructure is the biggie. In the US anyway, we already have a backbone of natural gas pipelines that go to most areas of the country.

And CNG is already being used on busses, trash trucks, and tractor trailers every day. I had a CNH civic that was a great little car, and basically identical to the gasoline version except for range. Honda stopped making them due to lack of demand. Bummer.
