This is a humours political stunt of some kind. It is done in Brazil and is directed against those that tend to park on parking lots reserved for disabled people.

A year ago Majken Jul Sörensen defended her dissertation at the University of Wollongong with the PhD “Humours Political Stunts”. It is an excellent analysis of the role of humour in resistance, a book a very much recommend. It is now available through the publishing house Irene that specialises in literature on nonviolent activism and resistance research. Check it out!
