Guides

Choose a realistic average speed

Route distance divided by the speed limit is not the same as real journey duration.

Use a realistic fuel-consumption input

Consumption can vary between motorway, city and loaded driving.

Split road-trip costs clearly

Agree which costs are shared before dividing the total.

Plan stops without hiding them in drive time

Explicit stop time makes arrival estimates easier to adjust.

Build a road-trip budget

Fuel is only one part of the trip cost.
