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.
The situation you are describing where a car owner returns to their vehicle, fails to see their four flat tires, fails to notice the note on their windscreen explaining that their tires have been deflated in protest, fails to notice their car’s tire pressure warnings, and drives any way, and drive enough to ruin their tires AND wheels seems unlikely enough to qualify as catastrophizing. The far more likely outcome is that the owner returns to their car and then spends some time, perhaps an hour or two, figuring out how to reinflate their tires.
I’m sure the individuals taking part in these protests also support politicians who desire stricter regulations about the types of vehicles they are targetting. Participating in peaceful protest and participating in a political process are not mutually exclusive.
