Navigate me to a gas station that is on my way rather than a gas station that is nearest to my current location. That will be suitable for drivers that wants to pass through a gas station but it is not that urgent to them and just don't want to get off track too much that could stall them.

The closest overall might be 2 miles from my location, but Waze knows my route, the closest only might be behind me meaning a 3 miles away gas station might be a lot more reasonable option as the "added mileage or time" will be simnifically less
