Yes. And rejection means little. The point is that adversarial examples have to be fragiley constructed to fool on one single example for one forward-pass. There is no evidence that any adversarial examples exist which can fool an even slightly more sophisticated CNN, fool a simple CNN over many time-steps, fool a simple CNN for enough time-steps to lead to any noticeable differences in action, fool a simple CNN for enough time-steps to lead to a noticeable difference in action which could lead to an accident, or fool a simple CNN for enough time-steps to lead to a noticeable difference in action which leads to an accident frequently enough to noticeably reduce the safety advantages.
