Google Maps blog:

Whether you’re heading to your hometown or exploring a new city, you can use Area Busyness, a new feature that combines live busyness trends to help you instantly spot when a neighborhood or part of town is near or at its busiest.

And:

Want more info? Tap on a neighborhood to see how busy it is at different times of day, along with the restaurants, shops and recreational places (like a museum) within it, so you can decide if you want to visit.

And for malls, airports, train stations, etc.:

To help you find your way around large buildings fast, we’re expanding the Directory tab globally on Android and iOS for all airports, malls and transit stations around the world. Now, when we have this data available, you can quickly see what types of stores are in a building (like toy stores or jewelry boutiques), airport lounges, car rentals, parking lots and more. And within each category, you can see a list of the relevant businesses, in addition to helpful information about whether it’s open, its rating and what floor it’s on.

And “pickup with Google Maps”:

Once you place your order from the retailer, pickup with Google Maps lets you track your order status, share your ETA and let the store know you’ve arrived, all from the app.

And:

As of today, it’s now available in over 2,000 store locations in more than 30 states across the U.S. People who use pickup with Google Maps typically wait less than five minutes for their groceries, meaning you can grab exactly what you need and get right back to your day.

This all feels like a challenge for Apple Maps, especially the funneling of store order pickup relationships to Google Maps.
