This is definitely pie in the sky but I dream of a future where you have so many autonomous vehicles all the road that we can not only collect this data but also incentivize the slow turning wheels of government to fix it.
Ok but where is the public Maps overlay for this? Is it available?
Google is offering this as part of the geospatial platform that they market to governments for huge $$$ so I don't think you are going to get it for free any time soon. Maybe limited access if you have an Earth Engine developer account?
Waze has this, and it works off of the same underlying data IIRC. It pops up a "history of accidents" note.
