I find it's the opposite - when you're traveling faster than the average, you are constantly adjusting your speed or having to change langes, as you come up on traffic from behind. You also get frustrated at nearly every car that slows your progress, especially if they're blocking all lanes. If you're going slightly slower, you can just stay in your lane and cruise. Cars occasionally pass you, but that's it. It's way less stressful. Plus there's always someone going faster than you, no matter how fast you go.
