Nope. These type of regulations looks good, but it's not fun or easy to do business in an overly regulated marked. If this continues, the US will improving financially faster than the EU. People are not likely to move to a worse economy because they value regulations like this.
Most employees don't seem to be in support of the unions at this point though? It's a bit hard to tell as there are no official numbers, but from what I've seen it seems like ~90% or so of employees at Tesla remain at work. And there is a high demand for their services, so they could easily go to other companies for work if conditions are bad.
Lots of companies work without collective agreements in Sweden though. Under law it's completely free if you want to do so or not. You could as well say that the unions are threatening the Swedish model due to taking this to such extreme levels. Especially as it doesn't seem most employees at Tesla want the unions involved.
No, you got it quite right I think. The government agency in question has a deal with Postnord (owned mainly by the Swedish state) to utilise them for all mail services. License plates has to be sent by mail. Postnord employees refuses to do so to Tesla. I believe they've also said they'd refuse to hand them out to Tesla should they come asking for them. In effect, not legal way for Tesla to sell cars in Sweden at this point.
Gun violence and these explosions have been going up quite a bit last few years at least. Anecdotal (Sweden here) people in my closest circle feel a lot less safe, and less comfortable in public spaces, compared to a few years ago. Not to a huge extent, but noticeable.
Wouldn't that just end up in the hands of whatever government is relevant? I believe the fines you pay for GDPR violations are paid to governments, not users or suers.
