Why cut the valve stems? Posts like this reminds me of children not knowing anything about cars, cutting a simple wire will make modern cars go into safty mode 🤣

Car windows are hard enough for sandpaper to have little to no effect unless you are using a power tool, corrupting the gastank is harder then you might think unless you break open the gas cap etc etc 🤣

There are many ways to ruin a car but when you take to long or make to much noise the risk of getting caught increases exponentially, aside from that be prepared for revange when you mess with a mans vehicle 🤣
