If what you say is true, the Lyft app may still be using the Lyft map. That would lead Lyft to conclude that drivers were using their map.

Another open application or another device would not show up in the Lyft analytics.

I'm sure they take into account whether the driver is following their app's suggested route. If the driver disregards the suggestions that would suggest the driver isn't using their maps.

If this is how they're attempting to measure it, then the only thing they've actually verified is that their maps are 98% as good as the competition.
