The average car purchased in 2023 emits higher levels of carbon dioxide (CO₂) than its 2013 equivalent. This is due to the large proportion of SUVs in the mix, which tend to be bigger and heavier.
I just learned about the Tyre Extinguishers. They use lentils to depress the pin on the valve cap of an SUV's tyre, so that the tyre deflates without getting damaged. It's super effective and it's not a crime. They are called the Tyre Extinguishers.
In the worst case they don't notice and lose control on the highway and die. I'm pretty sure that's illegal. This is hardly different from suggesting to cut their brake lines.
