Pretty sure that gps is a plaintext broadcast. It’s nice because it’s universally accessible, but it’s a target now that people rely on it.
Back in the 90s my head was full of maps of my region because I drove a lot for work. Mobile online GPS is a game changer, since you get traffic updates in real time. While I suppose you could review your route ahead of time, there is not a known way to get relevant traffic updates unless you have a radio station just to that effect.
My real concern for you would be a sudden information blackout.
