Google Maps seems to remove features with every successive release of Maps for Android.
You used to be able to measure distances on the mobile Maps app, but not any more.
You used to be able to plot a course or set waypoints on your desktop computer with its big screen where you could see a lot more, then pull up that route on your phone with the mobile app. Not any more.
I used to be able to publish a link to my location plotted on an embedded map on my personal web site so my friends could track me on road trips. They took that away claiming that idiots were forgetting about their public links and violating their own privacy. So to protect people from their own stupidity, ostensibly, they removed that feature.
I've forgotten all the features that they've removed just in the past couple of years.
In recent versions Maps INSISTS that you turn on wifi in order to get an accurate plot of your location even with GPS already enabled. This tells me that they continue to map wifi access points as you move around to add to their database. It has nothing to do with improving the accuarcy of your location, that's BS.
