It is more expensive. The fleet is probably growing faster than you know. At $1.50 to $2.00 cheaper than a gallon of gasoline on an energy equivalent basis, a lot of people might be interested in a vehicle that could use natural gas.
It would better yet to have a multifuel setup. With enough natural gas capable cars on the road, the traditional raping of the masses when gasoline prices were routinely jacked up such as around Memorial Day and Labor Day would be a thing of the past.
When you think about it, a $1.50 to $2.00 savings per gallon would extremely appealing.

Aggressive “go for all the oil we can get...” policies and President would also probably cut gasoline prices in half.
Thus significantly denting the advantages of natural gas.....
Will we see that?
Only God knows.....
