Don’t worry people - the planet is saved.
The “Tyre Extinguishers” are deflating tyres of 4x4s because, according to them, 4x4s are vain and cause global warming (or whatever it’s called this week). They’re also letting down the tyres of electric 4x4s because, they say, they cause congestion (even though in the real world where normal people live a 4x4, electric or otherwise, occupies the same road space as a hatchback).
Their noble and just cause will surely save us.
