I've never seen that before but that doesn't mean it isn't real. Perhaps it is a market area test thing but it could also be a custom route on the web version of Google Maps where you drag the line over. Just like that user tried to manufacture hate for G Maps a few days ago complaining about a ridiculous route to Burger King in another country but it was actually the Magic Earth Navigation & Maps application.

I've been looking into something like OsmAnd and OsmAnd+ (uses OpenStreets and Maps) because I want better feature sets, specifically features that are locked behind G Map's having to set a destination. OsmAnd also has some pretty cool plugins like Parking Position, Mapillary (for Google Streets-like views) to bring it to closer parity with G Maps but also Weather to show weather forecasts along your route on-screen and External Sensors so you could put your Bicycle Fitness stuff (Ant+, etc) on-screen and record it on the recorded route.

I previously looked at TomTom AmiGo as a sort of trial for TomTom Go but I didn't like the routing sometimes and with TomTom Go you need to pay a subscription for stuff that shouldn't require one.

For example, features such as showing traffic congestion around you, accidents up ahead and showing the speed limit of the current road you are on only shows up when you put in a destination. This feature has been asked about for years on Google's forums yet it still hasn't happened. I believe Waze does this but I don't like constant ads.

I'm definitely OK with paying for apps that are useful and prefer it.
