I don't think Tesla ending up exiting the Swedish market is the owngoal you think it is for Sweden.
Discovering this Swedish 'quirk' then vs. now wouldn't make Tesla any more likely to roll over to extralegal bullying tactics.
The right to strike is enshrined in the Swedish constitution of all things.
How exactly would it be "bad for Sweden" if Tesla never had entered? Tesla is just another large company. Why would it bad for Sweden if Tesla didn't enter their market because Tesla didn't want to comport itself according to Swedish laws and customs?
Polestar is in turn majority owned by Volvo Cars but also traded on the New York Stock Exchange, having to abide by rules there
Also, remember that time when Elon Musk claimed he would make Tesla private in cooperation with Saudi Arabia?
Also speaking of Saab: The Emily GT is set to start production in the old Saab factory soon, if/when that happens it looks like a solid Tesla Model S competitor.
Lastly: Remember the Tesla Semitruck? Well, Volvo and Scania is performing a bit better there… And Northvolt is supplying them batteries, and the Swedish carbon free steel will soon provide them great raw materials…
None of the other brands have issues to operate in Sweden.
I think the Swedish will be fine.
