Waymo's system is surely safer than Tesla's, though it hit and ran a cyclist in San Francisco and is being sued by another cyclist for an injury crash involving two Waymo robots.

Good question. Sounds like the bicyclist asks Waymo for the name(s) of the passengers and Waymo declined:

Waymo "intentionally declined to take steps to identify or disclose the identities of the passengers involved," according to the lawsuit

hi John~ i’m really interested in how you arrived at the ~20X figure compared to human drivers in SF. Would you be open to sharing your data analysis or methodology?

would love to understand the source details and math behind it!

Appreciate the important work you’re doing here!
