I have made plenty of long distance drives through some of the flattest and most desolate parts of this country and I have never seen cars going anywhere close to 100mph on average. Mostly 80's to 90's. One huge reason for that is fuel efficiency, which is dogshit even at 90mph. The other is that most cars really don't handle great past 90. And another is that you're far more likely to end up a fine bloody mist if you do happen to collide at that speed. Not likely, sure, but those speeds also come with vastly reduced reaction times.
