A long drive is a shared project with a fixed deadline, and the best ones run on unspoken agreements. Rule one: the driver chooses the music, the passenger curates the snacks. Rule two: whoever navigates does not argue with the driver about turns — one voice gives directions, and one voice drives.
Rule three: stop every two hours whether anyone admits to needing it. Fuel, coffee, and ten minutes of walking reset the driver more than any window rolled down. Rule four: the person who naps sets an alarm — a rest in the passenger seat is a courtesy, but so is a driver who is never alone in the silence.
The deeper rule is simpler: the trip is the point, not the destination. The best road trip stories are about the wrong exit, the diner that served pie at midnight, and the detour that took forty minutes and gave back a lifetime. Plan the route, then leave room in it for the unplanned.
