The above subject line is appropos. After several hours on the road, you can find your mind drifting and not paying attention. This, of course, is a major cause of accidents. It's sometimes called "highway hypnosis."
I agree with Bob, that stopping every 2 hours is good.

To make 572 miles a day, you'd have to be driving more than 10 hours/ day. Not a good thing. Is there a necessity to travel 5100 miles in 9 days? If not, slow down a bit and enjoy the drive.

Have a safe trip.
