Choosing the nearest gas station

The suggestion is that the technician should select the nearest gas station with a short interval. Sometimes it turns out that the excavator is choosing the nearest gas station (as he thinks) he chooses the one that is closer to him in coordinates, but in fact such a gas station is located behind a mountain range. And he drives there safely, passing several others along the way. Then it returns, burning fuel.

your excavator shouldn't be driving for fuel if you have fuel stations built
give at least one fuel station a truck, it will go TO the excavators to fill them

Also, this can probably be solved with logistical zones... Not that that doesn't introduce additional complexities of its own.
