Craig,
I lived in Barstow for a few years and traveled to Vegas several times. Yes, speeds are regularly 80+ mph. Slowing to 70 mph puts you solidly in the slow lane.

This would be, however an excellent test bed for the high speed stability of aerodynamic improvements. Winds can vary alot from headwinds, sidewinds and tailwinds and can be pretty strong too. There is a pretty steep pass in there between Baker and Stateline that will tax horsepower, especially with a headwind. I dare say this stretch of road is probably one of the most demanding higher speed roads in America, especially on a 120 degree summer day, and that horrible stuff they call gasoline in California.
