I imagine people will be more tolerant of a slower ride if--as a passenger--they can be engaged reading a book or watching a movie or whatever.
Not just because it's easier to pass the time, but also because there's no push to make the experience of driving "more interesting." (Too much, and someone drives unsafely, too little, and they aren't really paying attention.)

Given how commonly understood this situation is, I wonder what fraction of the population can read a book or watch a movie while riding in a car without getting fairly sick.
