The problem is that while Google Maps is very popular, it's not easy to find and use these features. I just came across is accidentally one day. Or it's possible Google asked me if I wanted to save if when it detected I do it often. It's been a while so my memory is a bit hazy on the original workflow I took.
While talking about hard-to-find-and-use features: sometimes, when I try to get directions, Google offers to download them for me for offline use.
This is frustrating because it only happens sometimes, but I want it almost all the time. There's a relatively easy way to download offline directions for a specific region, but I can't find a way to download offline directions for a specific route (including, presumably, a small fuzz of nearby information—I don't know what it downloads when it offers, since I find this hard to reproduce). Just downloading all the regions involved is impractical for, e.g., cross-country drives.
Do you know how to download offline directions for an arbitrary route, when Google doesn't prompt me to do so?
The only complaint I have about maps is that it doesn't seem to know where I'm going next. Nine times out of ten the place I'm navigating to is the same place I navigated to from the same spot yesterday.
