Google Maps may silently be Alphabet's most powerful property. As someone who has spent the last 8 months religiously degoogling my life, I've found that Google Maps features are incredibly hard to replace, while at the same time, giving Google direct abilities to influence behavior in the physical world. People see it as "just a map", but it's so much more. OSM-based map tools are pretty good as maps, but they utter…
But what OSM lacks is real-time integration with public transport. If my bus is slow or redirected Google will tell me. I don't think this can be improved by the users. It really needs a data feed from the transport operators :'(
