Gas or diesel ... modern engines pollute so little that we should change our EPA rules.
The Japanese model of not allowing older cars without special tags would end up saving us pollution and, maybe some money.
But try to get the greenies to admit anything like that ...
Greenies want to stop all individual transportation, EVs are just a means to an end for them. They know it will be such a clusterduck, that people will just say screw it, and opt for mass transportation.
