It turns out, there are plenty of idiots in the California state legislature, and they were sure that they could force drivers to go electric car by 2035

and push the issue by making a law that would require no internal combustion engine vehicles would be sold in California after 2035. 

This is exactly the same idiocy that passed a law that would require nothing but electric cars be sold in California after 2008. 

Yes, nearly 20 years ago the green morons had passed a law that was obviously a century before it's time, and had to be thrown in the dumpster when reality could no longer be avoided. 

Now the federal DOT is taking California to court to get that 2035 law thrown out, based on their point of view that no state gets to set fuel economy standards.
