> intelligence is needed for safe driving... won't get when something unexpected arises as it always will in time

I don't think that's true. While unexpected situations do arise, I don't think people use much "intelligence" to handle them. When an elephant falls out of the semi truck in front of you, your response is to hit the breaks. You don't spend a minute thinking about the likelihood of the event, or question whether allowing the elephant to hit your car might improve the likelihood of it surviving (and whether that justifies sacrificing yourself.)

The fact is that most accidents aren't very atypical. They're everyday things that happen, and people aren't paying attention, or they make a mistake. Handling just these scenarios will result in net saved lives. In other words, autonomous driving doesn't have to be perfect to be useful.
