The feature was first spotted by Google Plus user Kevin McLaughlin and doesn’t appear to be dependent on navigation. The phone detects that the user is driving down a route that, we assume, the user has used before, and shows nearby gas stations, along with directions, distance, and the detour required to reach each station.
It would be really nice if Google were able to pull in gas prices for each station, but even in this form, the feature can be very useful. With that said, checking gas stations on Google Now isn’t something you’d normally do while driving, but perhaps Google has bigger plans for this feature.
