Other

Analyst brief

The 'other' category is the largest grouping shown, spanning six companies — Tier IV, Metrolinx, Waymo, the Uber Eats delivery robot operator, and Nishi Tokyo Bus Co. — with index values ranging from 6.4 to 24.8. Severity across entries is mixed, from severity-1 malfunctions to a severity-3 injury involving Waymo, with most non-Waymo entries clustering at severity 1-2 and appearing as single, isolated rows. Waymo is the clear outlier and sole driver of the elevated band, carrying four entries across three years including a recall and an injury, while the remaining five companies each hold one low-severity entry. The dominant pattern in this category is concentration of risk in one operator (Waymo) against a broad base of isolated, non-recurring incidents elsewhere, spanning transit, delivery-robot, and robotaxi subsegments with no single common failure mode across the group.

Company risk ranking

Index 0-100: each documented incident is weighted by severity and by how well-sourced it is, discounted as it ages (half its weight every 3 years), then summed per company and scaled on a log curve so the highest-risk company worldwide is 100. Rank in industry: position among companies in the same industry that have at least one documented incident. Band groups the index: Critical (75+), High (45-74), Elevated (15-44), Low (under 15 with at least one incident); None documented means no public incident was found, which is not proof of safety.
