What you’re referring to is that the car will send a notice and update the fleet to avoid that area.
Actual changes to the maps including crosswalk changes and other permanent structures require review and update. It is not done automatically.
————— From the article:
If a change in the roadway is detected, our vehicle can identify it, reroute itself, and automatically share this information with our operations center and the rest of the fleet in real time.
We can also identify more permanent changes to the driving environment, such as a new crosswalk, an extra vehicle lane squeezed into a wide road, or a new travel restriction, and quickly and efficiently update our maps so that our fleet has the most accurate information about the world around it at all times.
> *We’ve automated most of that process to ensure it’s efficient and scalable*. Every time our cars detect changes on the road, they automatically upload the data, which gets shared with the rest of the fleet after, in some cases, being additionally checked by our mapping team.
They are literally saying they've automated most of that process and that was 2 years ago. That's completely opposite to what you are claiming. If you don't want to believe they can do it, suit yourself.
Go ahead and get behind the companies that need training wheels and rail guards. I’m going with Tesla which will be the first true FSD solution
