What an incredible post. I just love this guys blog, I wonder how long it took to research all of this. As a side note this gives me great confidence that Waymo will come out of the self driving car race in pole position.
Each time justin writes a blog post, I feel like a cartographer for a couple of minutes.
I love the attention he puts to the evolution of mapping services.
The only better thing would be the same blog as a post mortem from Google where they discuss the reasoning, design and tech behind these changes.
