This tenuously mounted rooftop stove strikes me as a fairly effective way to keep people back from vehicles on the highway. I know I did not want to get too close!
Those bumper stickers which read “Stay 500 Feet Back” that many emergency and village vehicles use seem poorly designed, since you need to be closer than 500 feet to easily read them. But a dangerously attached heavy object that looks like it’s about to fall off the back, I can understand that from quite a distance, thanks.
