CNG is already used in many public busses and gas industry vehicles. Burns clean, engines last longer. It’s fairly cheap (several thousand dollars) to make a vehicle able to run either gasoline or CNG.

The downsides are:

1) The need for an additional CNG tank
2) Starting an engine with CNG is difficult in cold weather
3) CNG has less energy output than gasoline, making it less efficient for towing and hills.

All of the downsides are manageable, and the auto industry looked like it was headed toward stock dual fuel use vehicles UNTIL Obama was elected and pushed them to electric.

2) Starting an engine with CNG is difficult in cold weather

I have absolutely no experience of it, but just on the basis of the high volatility of NG compared to gasoline, the natural assumption would seem to be the opposite.

Can you explain?

Absolutely! This was a bottom up technological change that was killed by Obama.

Maybe the answer even there is to run on dynamically switchable fuel, or turbos.
