I am Swedish and I've never heard of the Sweden Sans font before. The font doesn't look very "Swedish" to me and is completely different from the font used on road signage, for example. For running text the font doesn't work at all imo.
Road signage is actually a very specific and typographically demanding use case with its own whole world of constraints and consequences. It's everywhere so very mundane to us, but it's not surprising at all that a general-purpose font isn't usable for it.
