Isn't Waymo rate better because they are very particular where they operate? When they are asked to operate in sligthly less than perfect conditions it immediately goes downhill https://www.researchgate.net/publication/385936888_Identifying_Research_Gaps_through_Self-Driving_Car_Data_Analysis (page 7, Uncertainty)

Waymo vehicles primarily drive on urban streets with a speed limit of 35 miles per hour or less
Teslas do not.
