Agreed - I'm curious how they are able to globally deploy so quickly where others (apple / tom tom) take FOREVER to update.

Do they just have someone ground truth with satellite and street view? They do have that data for most of the corrections I make (which are frankly rare).

Waze has volunteer local editors - I've hit "report map issue" and gotten messages from them with questions about what I was reporting. I wonder if Google leverages them internally.

Are temporary closures automated? I feel like in Waze I gave them enough information when reporting about things like construction or flooding that they could be integrated almost immediately--similar to road hazards or stopped vehicles.
