People are making the predictable error of thinking this very new technology should be perfect. That's not a reasonable expectation. Newsflash: the first truly autonomous vehicles (which this IS NOT) are going to screw up sometimes. They're going to get people killed. They should, as a minimum standard to be allowed for use at all, get fewer people killed, but it's not going to be zero, and it's going to be a different set of people.
It seems to have left all the decisions up to the dumb driver.
A lot of people aren't comfortable with giving up control over their car. While I'm not one of them (the day I never have to drive again, I'll be thrilled!), allowing the driver to make the decisions when they want to may be a requirement of a commercially viable product.
