Expectation: everything is packed, settled, and working exactly as planned.
Reality: the unexpected overlook has other ideas. Small routines for routing, rest, cargo, visibility, and stops make long-distance driving calmer and more adaptable.
A little patience, a quick check to build time and fuel margin into the route, and a willingness to laugh at the timing usually restore order. The story gets better once the problem is behind you.
Good thing staying calm and flexible usually gets things back on track.
