The mapping problem keeps getting brought up (often by Tesla enthusiasts).

It just doesn't seem like a huge problem? If you have cars equipped with high resolution Lidar and cameras, mapping new routes seems like it ought to scale as the fleet is expanded.

This problem seems embarrassingly parallel.

I don't understand. You first need the map, then you can drive, yes? How does the fleet help in the creation of a new map?

The fleet car drives very slowly the first time, perhaps under supervision of a human.

The point is - you have a massive fleet of cars with all the right sensors to create a high resolution map.

As a reminder, Google Maps Street View was brought to us by Google. They might know a thing or two about mapping the drivable (and more!) world.
