As someone who took driver's ed, it's odd how many people are using their brakes on the highway in good traffic just so they can stay in the danger zone where they have no time to react if the car ahead of them stops suddenly (even if they're in the right lane and not actually trying to go fast). Out of pure greed you'd think people would realize they're burning their gas and brakes for no reason.

I'll add that on the highway, you can scan way further ahead than you're used to. You should be able to maintain focus far ahead and use your peripheral vision to keep between the lines on turns. It's not the easiest thing to do, but it's very easy to practice.
