Have you ever calculated your average speed? It's surprising how low it can be. If you cruise the highway at 60 mph, just the access road and parking lot segments at either end will drop it to 55. Stop for gas or restroom? That's easily another 5-10 mph lost. Meals, since they were driving all day? Another 5 or more.
