Very nice analysis by neurosurgeon @slotkinjr of how @Waymo's autonomous vehicles have much better safety properties than human drivers， and what would happen if everyone in the U.S. drove as safely as a Waymo.

"The national math： If every US vehicle performed like Waymo， we'd prevent 33，000-39，000 deaths annually and save $0.9-1.25 trillion in societal costs. Even partial adoption at 27% would save ~10，000 lives per year. In terms of magnitude， this would be the equivalent of eliminating every pedestrian death nationally in a year."
