Engineering the software that keeps self-driving cars operational involves incorporating a number of factors, from the presence of pedestrians to weather conditions. Traffic signs are also critically important;

A power outage in San Francisco caused autonomous cars to just freeze wherever they were. Apparently, Waymo engineers never thought to include a basic “pull over and park” fail-safe. 🤦🏽‍♀️

Waymo robotaxis stalled during a major power outage in San Francisco, contributing to citywide traffic disruptions.

On its website, Waymo states that "compared to an average human driver over the same distance in our operating cities," its autonomous vehicles have 90% "fewer serious injuries or worse crashes;" 82% "fewer airbag deployment crashes," and 81% "fewer injury-causing crashes."

Multiple videos show Waymo autonomous vehicles illegally passing stopped Atlanta school buses, triggering federal scrutiny and calls from Georgia leaders for stronger oversight and even halting the vehicles.

Waymo has begun testing driverless cars on Tampa streets as the company prepares for a future passenger rollout.
