They have that, and these cars completely depend on it for fundamental parts of the stack. If they detect that their understanding of the scene doesn't match their map, they (generally) have remote operators clarify the best course of action for the car. This isn't a remote takeover - they just plot a path for it or select from a number of different options the car presents to them, or give it the all clear to proceed. I worked in the AV space for years - not at Cruise - but during one of my first driverless rides in a Cruise car, we ran into a few blocks of SF where the power was out. About 3 street lights in a row weren't functioning. At each one the Cruise stopped completely for about 45 seconds before crossing - even if there was no traffic coming from it's left or right. That delay was so that a remote operator could clear it to proceed after it detected that there wasn't a functioning street light where it expected there to be one. After the first street light we were getting honked at and swerved around by cars behind us while it paused and waited for clarification. Comparisons between the safety of robotaxis and human drivers are strange to make when 'robotaxis' still depend on remote operators for fundamental parts of the driving task
