Perhaps the last time we had this much change proposed was between 1970 and 1975.
The difference then was that the Government tipped the scales with regulation causing the change and industry opposed it.
Today we have the social force behind the global Climate movement and the Paris Accord vs the US Government where the federal Government has withdrawn from the deal but several states along with several large corporations (who do business globally) are apparently still voluntarily going to comply with it.
On the bright side the price/value of a well maintained used Gas engine vehicle could be set to increase in value.
