And that is the United States, and that is because of Donald Trump. From WaPo:

The Trump administration on Thursday announced plans to freeze fuel-efficiency requirements for the nation’s cars and trucks through 2026 — a massive regulatory rollback likely to spur a legal battle with California and other states, as well as create potential upheaval in the nation’s automotive market.

The proposal represents an abrupt reversal of the findings that the government reached under President Barack Obama, when regulators argued that requiring more-fuel-efficient vehicles would improve public health, combat climate change and save consumers money without compromising safety.

Trump’s plan also undercuts California’s long-standing ability to set its own tailpipe restrictions, most recently in an effort to curb greenhouse-gas emissions.

What is the rational for this? There is only one. Hippie punching. He is showing his base that he has yet another way to make the liberals cry.

But guess what. The liberals will not cry. But they will fight.
