What you’re looking at is a salt circle, a traditional form of protection—from within or without—in magical practice. In this case it’s being used to arrest an autonomous vehicle—a self-driving car, which relies on machine vision and processing to guide it. By quickly deploying the expected form of road markings—in this case, a No Entry glyph—we can confuse the car’s vision system into believing it’s surrounded by no entry points, and entrap it.
I am afraid of the distance between the individual & power. Once it comes out of the hands it becomes an instrument of destruction. But why, oh why do we never know who to blame in these cases. The countless cases, in fact most all cases today are this way. The rampant destruction. Because the individual succumbs to the loss. All things destroy. & no amount of insight can find who is at fault. The state stands over the people & takes. The people, blame the state. The people blame the other side. They blame someone other than who has in fact committed the original crime. The one crime that is the cause of all others. The individual, at a loss.
