Except, as I pointed out in
a post, we do seem to limit the number of autos imported into the US (and it also helps explain why US cars don't sell well, as a general rule, in Europe). As I explained there, we have a very complicated and expensive process for manufacturers to certify that various car models meet emissions and safety standards, and this prevents companies from offering many of the cars available in the EU, Japan, or Korea from being sold in the US. Many people claim this is a way of not having a tariff but still preventing companies from importing cars.
And that is ignoring the "
chicken tax," which is a 25% tariff on light trucks, to include pick up trucks and vans.
This article gives a sample of the trucks that aren't sold in the US because of the chicken tax. Perhaps the issue is that we think we can limit imports into our country while telling other countries they have to buy our cars (so that we don't have negative trade deficits).
