Amtraks stop for 20 minutes every 30 minutes to let passengers on and off at each stop. A car journey only stops if you need gas (15 minutes) or if you need to use personal facilities (10 minutes). Furthermore, an amtrak will only hit a top speed of 79mph, and only a few times during the journey, while a car can stay at 75mph for most the journey.
