They claim no new gasoline cars will be sold here after 2025.
So there will be anti-importation rules and smuggling and grey market cars, just like for exclusive foreign luxury cars, which are not US certified (and never can be.)
With wealthy folks continually flaunting the rules (as they can spend $$$ and do now) more new rules will come about to tax and restrict everyone’s IC use.
Which will engender another round of costly/complex loopholes and $$$ flaunting, ad naseum.
Over time, all these high-level mandates seem to blow back and forth like the March wind.
When I was five, (1960) the big goal was universal electrification, and the all-electric home. It was at Disneyland! It was our future! My grandparents heated with oil, but our house had all-electric heat etc.
No wood, oil, kerosene, coal, propane, natural gas or other stinky fuels. Safe, clean, efficient, ready kilowatts! The gov even promoted it with cartoons to us kids.
Then somehow, the cost eventually became staggering, from demand plus poor supply-side coordination and no new engineering. Instead of fixing that, they sent us all on a slide back into home combustion of heating and cooking fuels.
Even though it was cheaper, cooking with gas actually became fashionable among the posh again! Like it was Victorian London! “Put on the kettle, hey Watson?”
So here we all are, cooking and heating with gas, and looking at friends actually burning wood for heat, like the 1800’s again. Polluting. Again. Phoooie!
But wait! Now gas cooking and heating are to be outlawed by 2050, and everyone will likely be mandated to have solar panels. Then everything will be electric, again, just like our house in 1960 (so they say…) Only more expensive.
So in the course of 90 years we will have managed to reverse course twice. Yet, I can EASILY imagine it happening again, and well before 2050.
