People who live where Waymo tests their cars often say they were initially afraid of them. After a few months however many of them say they feel safer because Waymos don't text, don't drink, don't drive aggressively and don't argue with their their kids while driving.
When Waymo can show their cars have less accidents per 100,000 miles than human driven cars, I predict a big shift in attitude. People will wish parents got their teens a self-driving car. If they show Waymo taxis are safer than human driven Ubers, I know which ride service I'll hail.
Here is what it is like to be in a Waymo taxi. The complaint is how conservatively they drive.
