One additional note: Honda is also selling a CNG plug-in compressor that taps a homeowner's residential natural gas system and refuels the Honda overnite. (4,000 PSI)
So, an owner need rarely even visit a commercial refueler.
The compressor keeps track of the delivery... so that any tax due can be paid. Presumably, the road fuel tax would be paid with your income tax return as just another line item and calculation.
