Yep - 3.5% of distance traveled (i.e. drive 1 km and you'd have 35 meters of drift)

  That's not that bad, specially for solo driving where you cannot use a regular road map (remember those?).

    Let me guess: you didn't ever solo drive for work. You can certainly use a paper map while driving. When it gets too distracting to safely drive then you are lost and should stop and use the paper map more thoroughly to find out where you are. Source: I intentionally tried to be a parcel delivery driver without a GPS-based navigation and only with regular road map and printed out rough plan of the route. Not to mention that for most of my long driving trips I used to simply print out the itinerary from RAC RoutePlanner and ignore the navigation (it is a shame that this service apparently does not exist anymore).

  Not bad. When you consider a city block is about 100m, you could drive 3km before being off by a street so as to miss your turn. On the highway it’s even better- if exits are 5km apart, you can drive 142km before being so far off you might miss your exit

    That is surprisingly close to what I used as a good-enough error in fallback route estimator in our TSP/VRP solver. I came up with that essentially by curve-fitting great-circle WGS84 distances and really traveled distances between my favorite pubs and it seems to work (bear in mind that it is the last fallback and there is A* on map data and ML-ish thing before that)

      Everything is fractal/self-similar
