When I drive long distance, particularly by myself, I typically get on the highway with a full tank and pull off when my low fuel light comes on. Depending on traffic conditions, this is typically between five and six hours. At the end of that I don't mind stopping for half an hour or more, but that requires far more than 200 miles of range.

When I do stop in the middle for coffee and a leak, it's rarely more than 15 minutes total off the highway (unless the service is slow).
