“But as the Tennessean article I just posted pointed out. Vehicle emissions is only 2%.”
Only 2% and unchanged in the past months. So whatever you are seeing it had nothing to do with ending emissions testing.
The EPA dropped the requirement because our air improved.
I don’t know why the air improved. But I’ve noticed it has.
In any event the vehicle emissions are only 2%, so were never going to have much impact.
