If you want to pressure Volkswagen, go ahead. Nobody cares. The fundamental flaw in your position is your implicit assumption about what we value or what motivates us. We're not Americans. I don't think America's "non-tariff barriers" are a valid concern. They are disingenuous rhetoric for domestic consumption. Heads would roll if there was ever an agreement with the US to lower our standards and open up local industries to competition from lower quality foreign importers due to geopolitical pressure. Pressure is not going to undo the DSA or the GDPR because they have broad support. As others have said, it is decades overdue. If Elon Musk is mad about having to follow the law, I'm sure he can find sympathy elsewhere. His sour grapes are not principled, they are about protecting his ego and finding others who do so for him.
Sorry for the bluntness, but I feel it is very much warranted.
