From the article: *Large SUVs were particularly affected. According to the police, notes were attached to the cars indicating that they were harmful to the climate. The tyres were not punctured, but merely deflated. The cars were parked in the area between the S-Bahn line and Elbchaussee around Kanzleistraße. *
Personally, I like this protest way more than glueing themselves to the streets, causing traffic jams where cars burn gasoline for hours and ambulances / firefighters / police gets stuck, putting innocent life in danger.
The article is in German. Warning: this link leads to google translate.
I am quite surprised to see how many people think that is is OK to pollute, hoard public space and make cities worst just because you had money to buy a SUV
