Leveling means nothing, and are determined by the company. Actual operations and range of operational capability matter.
That's what I thought too, but apparently it's not that clear cut. Their manual says that the driver must be ready to take over not only when prompted by the system but also "due to obvious circumstances". It's not clear what that means — cue the lawsuits. https://safeautonomy.blogspot.com/2023/09/no-mercedes-benz-w...
His suggested metric is cars/operator, which was ~20 IIRC.
For Tesla, for the near future, that number is 1.
Cruise has still been in and caused accidents, at a rate likely no better than Tesla. Also, Cruise operates only on a small number of mapped roads, whereas a Tesla can operate anywhere in the U.S. in most weather conditions, and yet still does a great job.
If Cruise had a fallback driver all the time, it would “operate everywhere” too. That’s not really saying much. The entire problem is about how to remove the driver, which Tesla is nowhere close to in any geographic area. A dead giveaway is how they’re reluctant to even let drivers take their hands off the wheel.
