tl;dr of the article:
- Autonomous vehicles drove fewer miles in the state of California in 2017, but maybe made up for that in miles driven elsewhere.
- The disengagement rate will probably need to improve considerably before AVs are ready for widespread deployment
- Waymo's disengagement rate barely improved year over year, but that may have been because they are placing the cars in more difficult scenarios (their blog post suggests that is indeed the case)
