1) Tesla does not report their numbers, though one person who went for a ridealong in the autonomy day demo reported one takeover in 20-minutes [1], so at least once every 10 miles. 2) Waymo does testing on a lot of types of roads. They reported 1.26 million miles in CA last year [2]. It's not possible to apples-to-apples compare this to Tesla's numbers because Tesla does not share their data. Musk even turned down an analyst's request the other day for details backing up his claim of autopilot safety [3]. Tesla/Musk are being unreasonable when they claim stats show their system is 40% safer or 2x safer than normal driving because they are comparing to NHTSA stats which include all classes of cars (including motorcycles), all road types (whereas AP is mainly used on divided highways), and all weather conditions (nobody activates AP in the snow, I hope, and I doubt many do in rain).
