Imagine having 9+ mostly-uninterrupted hours in a car, for reading. All those hours to read as much as you can. Heaven. Heavenly. Divine.
Unless you're me.
Unless you're me and you get pukey/nauseously sick if you even attempt to read a map, let alone a book, in the car. All those wasted hours! The torture! It's actually painful, irritating, upsetting. There's my book (one of 3 with me, actually), sitting in my lap, waiting, waiting for us to stop and fuel up so I can read one page before we drive off again.
That's my definition of an "awake" nightmare.
