To add to that: light trucks imported from other countries are also subject to a 25% tariff known as the the "chicken tax"[1], and if I understand correctly, light trucks are subject to more stringent MPG standards to the point that auto manufacturers won't make them. Whether this latter is "environmental regulation gone too far" or just a matter of regulatory capture by an industry that doesn't want to compete in a market where small, cheap trucks are a thing that exists is a matter of interpretation, I suppose. I lean towards the regulatory capture interpretation myself.
