Many of us are quite familiar with the reliability of software, and have serious concerns about trusting it to make the right decisions in a complex real-world situation.

As for humans, 35,000 Americans die every year on the roads and 6 million accidents occur.
I think we should be able to get software reliable enough to reduce that by 10x
There are almost 2 million rear end collisions in the US every year. Humans just don't have the reaction times to handle many situations. That is also best case. Many people are distracted while driving.
