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.
I wish this form of protest would catch on elsewhere as well. Every day I’m struck by the number of huge gas-guzzling pick up trucks parked around the city, and seemingly every bed completely empty. Letting out the air to their tires would certainly be slower and more work than the old method of puncturing their tires, but has the dual benefit of not necessitating replacement (which has a carbon cost of its own) and not enabling the vehicle owner to file an insurance claim.
I mean…here we all are…talking about it. Some people are being more civil than others, but some people are genuinely attempting to discuss the role of individual responsibility in the face of catastrophic climate change.
