@Wuzzy agreed on most points but on an ever so slightly different tangent, the Google maps app has(for my purposes) the best traffic telemetry on anything I've seen of recent times. For most, maps are a utility, and folk will want a map that just works, for them. I appreciate that it's slightly different than don't give your data to Google but similar in that the traffic telemetry is I think for a large part based on maps usage in the field.
