I'm not sure about Tesla being the leader in real world data. They have a lot of cars and video, but only in select countries. When I think of real world capture, I am thinking of Google with their street view and google maps. The amount of data they have is mind boggling. They are also able to scrape data off of Google Drive files that are set to public, so I don't think they're giving up that throne soon. But I do agree that Tesla won't be lagging behind.
