The correct answer is to not directly regulate autos themselves, but instead to implement a universal carbon emissions tax that would apply to any and all sources themselves (e.g. gasoline, propane, cement, etc), proportional to the amount of carbon emitted. No carve-outs or exceptions. No offsets. No protected industries. No change with scale (volume discount). Then you let people/companies figure out all on their own how to respond to that tax.

And yeah, the chicken tax along with all the other tariffs can go.
