I still use gmail and drive for work but otherwise I'm never logged into anything google at home. Today when I tried to expand on a restaurant's hours it wouldn't let me see them without logging in, although it still worked in incognito. This restaurant screenshot is just a random other example I tried, but for the one I was actually checking google had the correct hours while the official website hasn't been updated in awhile and had the old ones (website said they're still open for dinner but they've only been doing lunch for a year or so now)
I have tried open street maps it didn't even have my address correct. It was absolute trash. There are very few things that actually work and work well when you need them to work. I would never trust that service to work well. It relies far too much on individuals to fix everything wrong with it. I had to submit my correct address to it which took several weeks to correct. And that's just one address that I looked at that's a standard address no big deal shows correct on every other map out there but if I were trying to rely on that for life-saving services hell no.
