Have wanted to work on a "better situational awareness while traveling" app, but haven't yet had the chance. Reachability of a POI is a great place to start, and I _feel_ that "it's a lot harder than it at first looks" aspect.

It would also be cool to:

* Become aware of local attractions. Esp. good restaurants, shops, views, hotels, hiking trails, etc. A lot of rating systems seem to give every fast food venue 3 or 4+ stars. Impossible to sift out the truly good and local / unique from the chaff.

* Become aware of time-limited events. Fairs, art shows, VFD chicken BBQs or fish fries, ... all the little "I wish I knew that was happening, I would have stopped by!" I constantly search for the local, the offbeat, the not-yet-another-corporate-outpost. But again, the chaff!

* Be able to navigate on backroads and scenic roads. Mapping apps are so hyper-focused on getting you there fast. They're not good at "get me there happy"—at least not for those of us that value the path less traveled far more than the highest-speed highway.

In Austria, you have usually one exit. Alternatively, there might be a roundabout.
