Nearby references are selected by logarithmic distance, not linear spacing.

How long would this journey take?

Calculated as uninterrupted travel at representative average cruising speeds.

Real travel time varies with route, stops, weather and operating conditions.

Objects move along logarithmic spacing, while size is compressed from the real ratio to remain legible.
