&gt;Most of us are going to expect nothing short of perfection from these machines to really trust them.<p>Now, expecting perfection, and especially giving up &#x27;better than what we have&#x27; in exchange for perfection is a bad thing, but but I do think it&#x27;s completely reasonable to expect the self-driving cars to be way better than an average human, even better than the best humans, just because we lose so many people to auto accidents every year.<p>I think it&#x27;s completely reasonable to want to reduce the risks associated with transport, and I think the only politically possible way to do this is with self-driving vehicles, because I don&#x27;t think it&#x27;s politically possible to remove the worst half of drivers from the road without offering them similar levels of mobility.
