Who knows, maybe they stuck 65 mile/hour speed limit sign over a stop sign. That wouldn't fool a person. People use a massive amount of contextual data, historical knowledge, and common sense to interpret the world around them. A random out-of-place sign like a 65mph marker at a junction where a stop sign might be isn't enough to trick someone. Self-driving cars probably won't ever be as good as a person at this. That's fine because we're able to accept a small risk if the reward is enough of a benefit. Law-makers should be considering it and making "tampering with a road sign" a much more serious explicit crime that's worse than just basic vandelism though.
