Again, Tesla has factory in Germany. How are you going to tariff locally produced goods?

By adding 100% to the price on all cars sold that are produced from that factory as long as it is owned by an adversarial individual.

The factory can always be sold to another company.

What a wonderful way to make sure no foreign companies build factories inside EU.

did the russian sanctions do that?

elon musk is no different than your average russian oligarch

Which factory was forced to sell/close because it was sanctioned?

The same approach as the sanctions against Russia can be used against Elon Musk.
