Everyone is pointing at the others for the actual cause. The corporations that buy the stuff you move around in your truck should be targeted? Or the politicians that allow you to buy a gas gurgler (and ruin the environment) by driving it around without it being prohibitively expensive?
Or should you suffer because you bought the car and are driving it into city centers (where public transport is available, and most SUVs are not used for hauling goods)
They're not leaking the air out while the car is driven. Modern European cars all have pressure sensors and will warn the driver when there isn't enough air in the tires to drive safely. Saves you from walking around the vehicle to see if everything is tied and pumped up properly.
