On the interstates, I just follow trucks. They don't like to brake much or have to shift so they keep a steady speed. Bonus is that even at a safe distance behind a semi, there is usually still an aerodynamic advantage (slightly better mpg...obviously not as much as you would get by tailing but still not bad). They're often more conscientious and aware of their surroundings as well.
