&gt; It happens with great frequency.<p>I doubt it happens that often, but I can&#x27;t back that up with numbers, and I can&#x27;t be arsed to try.<p>But, humans can vary in their driving ability. In the case of autonomous cars, you would have to assume any flaw in one is shared by all. The problem isn&#x27;t the laser pointers, or that humans can also be disabled by laser pointers, but that autonomous cars aren&#x27;t yet smart enough to deal with errant signals. If all the autonomous cars can be stopped by an ever increasing list of simple conditions that (with a couple of exceptions, like a laser pointer in the eyes) wouldn&#x27;t stop an average human driver, then it implies that the current state of the art does not nearly live up to the hype.
