I'm not an economist nor a mathematician, so I will not claim that this is a good expression of the economic impact of these restrictions. But I will say that the average American does not care about which country his or her car originates from. They care about navigating our crumbling infrastructure through the only means possible, the car. We have no reliable public transport in 99% of this country nor alternative modes of transport. We are forced to buy cars.
It seems unfair to me that the average American, who is making less and less per year after we adjust for inflation and purchasing power, should be forced to carry the burden of a technologically backwards industry that is still pumping out millions of gas-powered vehicles, which are not only bad for the environment, but are even more expensive to operate compared to the cost of electric cars per mile.
Our country does not think ahead, all of our decisions just temporarily patch our longstanding issues. America is screwed.
But it's definitely more complex than just money saved = money spent elsewhere
