First, no one expect automation to be perfect, but people do have a reasonable expectation of it being much better than an average human driver. Most accidents (in good weather conditions) happen when drivers are distracted, tired or sick. This does not apply to an automated system, and even when something goes wrong the system should go into a fail-safe mode (in this case - stop).<p>Second, &quot;at least as good as the average human&quot; is a bad benchmark. Not because an average human is so bad at driving, but because people make high-level judgements about acceptable risks. For example, you are much, much less likely to dent your bosses Porch than some random car. AI is equally likely to hit either.
