原推：The HD-map-based robotaxis have gotten there by carefully mapping (and likely appending driving policy specific annotations) to all intersections
This works but doesn’t scale https://t.co/VHOtetPkjN
Accident and disengagment rates for autonomous systems should be compared per-intersection (rather than per mile)
Intersections really are the hardest thing
More than half of (human-caused) injury and fatality collisions happen at intersections
Same will likely hold for ??s
