You are correct that it probably won't be allowed. But your assumption that Sweden is restrictive isn't. I see that you live in Stockholm, so maybe you already know this, or you haven't spent much time outside the city in recent years. Almost every medium and small city in Sweden now features 16 to 17-year-olds driving old cars electronically or mechanically converted to only run at 30 kph (~20mph) without requiring a proper driver's license, adequate noise reduction, exhaust system and until recently not even winter tires or seatbelt. Making roads slow and dangerous, and the local environment much worse for everyone else.
Now I don't expect this to be well-received because of "cool hack" but it is truly a major issue. Other issues like the high housing costs, bad healthcare, lacking infrastructure, mediocre education and a short-sighted population are all hard to solve. But this issue is clearly a priority. Swedish voters and politicians are prioritizing this over providing a good quality of life at a decent cost to enable education, research and knowledge based businesses.
The result as a whole is that almost anyone who can is moving from these cities to bigger cities that don't have these problems, but are also so expensive that engaging in activates with high growth potential isn't viable. With grassroot hacking, small- and medium-sized business and major growth startup ending up being a fraction of what they have been and even more so should have been now.
