I have been using OsmAnd~ [0] lately and have been pretty happy with it as an alternative. Uses open street maps, works offline, pretty good and configurable app.

The big issue preventing me from using something like OsmAnd is my need for real-time traffic. Generally, I can figure out where a place is with only the address since the N-S streets in my city are numbered and the first digits of an address on a cross-street corresponds to the numbered Avenues. Traffic, OTOH, can easily vary by 30 minutes on a 15 mile trip day to day even without any crashes along the route.

Is there an open, or at least more private, app that can give me accurate traffic data?

Maps.me, which also uses OpenStreetMap data, can show live traffic info. Not sure where they get the data from or whether it's accurate.

User error. Don't use your phone while driving.

I wasn't in any real sense. Until of course the view of my next turn was obstructed... Are Uber drivers "using their phone"?

If they're fiddling with the phone while moving, yes. That's an automatic loss of three stars from me. Missing an exit is not a tragedy; hitting someone might be.

Don't touch the touch screen while the engine is running.

If I had a paid click for every time youtube has asked me to switch to their shitty tab-less app..
