SUV sales are booming, but not everyone is in love with modern high-rise family cars. One group vehemently opposed to SUVs has just claimed responsibility for an attack on a UK JLR dealership during which the tires on around 60 Land Rover vehicles were destroyed with a cordless electric drill.

A group calling itself ‘Tyre Extinguishers’ says its supporters ambushed the Vertu Land Rover retailer in Exeter, targeting scores of SUVs parked outside the showroom on Matford Way. A grainy POV video of the rubber wreckers in action was posted to the group’s twitter feed. Though it’s too dark to see the tires being drilled you can hear a ‘zzz’ from a power tool as one of the activists moves quickly from vehicle to vehicle.

Anti-SUV sentiment is nothing new, and neither is Tyre Extinguishers’ opposition to what it sees as grotesquely oversized and inefficient vehicles that pose an even greater threat to people and the planet than ordinary cars. It has been slashing SUV tires for over a year, though not on this scale.

But one recent even that has particularly fired the group up is the death of two eight-year-old girls in Wimbledon, just south of London. Nuria Sajjad and Selena Lau, both eight, died when a Land Rover Defender crashed through a fence and into their school yard on July 6. A 46-year-old local woman arrested at the scene on suspicion of causing death by dangerous driving was later bailed.

“In response to the tragic incident that occurred on Thursday 6th July, where a Land Rover SUV driver crashed into 15 people killing two innocent girls… Tyre Extinguishers destroyed all the tyres on at least 60 vehicles at Jaguar Exeter, Matford Way,” says a statement on the group’s website.

“SUVs are 8 times more likely to kill children in crashes, than smaller cars,” it continues. “Tyre Extinguishers firmly believes that their action is a necessary escalation to try and stop these vehicles from wrecking further lives and continuing to push the worsening climate crisis of the cliff edge.”

Vertu Motors, the owner of the targeted dealership, told The Daily Mail that it wanted to see Tyre Extinguishers activists punished for their illegal protest methods.

“Trespass and damage to private property are not acceptable”, a spokesman for Vertu told the website. “The matter is now in the hands of the police.”
