My main goal is to get a solo driver HOV lane access sticker for SoCal traffic. Secondary is to save on $/mile.
Pure EVs, plug-in hybrids, hydrogen FCs, and CNG vehicles can all get the HOV access decal.
The Honda Civic CNG is my next test drive. There's an adequate number of CNG stations around here.
Overall best choice may be a used CNG Honda.
There's also a home CNG refueling station, if you have the ability to install one in your garage.
