My own observeration from Stockholm is: beaches crowded during heatwave, public transit is crowded as usual. Lots of movement of people, travel within Sweden etc. Practically nobody is wearing a mask. People are still generally careful, washing hands, keeping the distance in lines etc, but I don't think this can explain the cases going down. In March-April, I think people were the most careful, when hundreds were dying every day. Since then people have gradually become more relaxed, but the numbers keep going down. Of course, it could be that these rather small measures have pushed r0 a bit under 1 ever since March. But there have also been reports that for each person tested with antibodies, two more are actually immune, which would put the immunity at maybe 30% two weeks ago. At least it's in the right ball-park, as some have proposed that herd immunity could be reached at much lower percentages than previously thought.
