I feel like part of the difficulty here is that if one Cruise car responds this way, it means that every Cruise car responds this way. So whereas you might have a few dumb human drivers who can't handle this situation and occasionally run into issues, if this particular Cruise car were mass deployed, you'd run into it frequently. On the other hand, it's possible that while the vehicle couldn't act correctly in this particular circumstance, it would act correctly in many similar circumstances, and thus the issue would still be rare.
