It's seen as a poor investment because over the long term, gasoline usage is projected to decrease with electric car adoption.

The combustion temperature of ethanol in air is very close to that of gasoline in air. If you vaporize the ethanol completely and then put it in a high compression ratio engine made to take advantage of the cooling effect, you'll have even higher temperatures than gasoline since the higher heating value is greater per unit oxygen consumed.
The
only way to meet current emission standards is exhaust aftertreatment. I wouldn't be surprised if natural gas stoves in homes produced more NOx per unit heat than cars are allowed
