Yes, a "pretty small use case" at somewhere around 10,000,000 trips per year on I-5 through the central valley of California. Or 9,000,000 trips per year each way on I-8 across the desert to the Arizona border.
On your daily commute, you may not need help navigating so much as you want accurate real time information about which routes are moving well compared to others. For me, trip planning and using a navigation device is not for local driving (I mostly use OsmAnd for local driving to help me find errors in OSM data) as much as for getting me to places I don't go on a daily basis. You could say it is a pretty small use case as most people don't drive to or through unfamiliar places everyday, but it is probably the biggest use case for a nav system there is.
