To your second point, google seems to have ramped up their efforts on micro mapping a lot in the last year. I frequently get a little questionnaire after using google maps to get somewhere that asks me to pinpoint exactly where the entrance of the building is, if there are multiple entrances, are they accessible, etc etc. Google also started rolling out more details on sidewalks, parks, etc in some cities, so I'm guessing they might transition that to more cities in the future. There are definitely gaps in some areas where google is quite far behind compared to OSM though. Trails is one area, I personally have spent a lot of time in OSM accurately mapping out trails in my local parks.
