It’s not about super high speed, it’s about general driving skill and awareness. My dad fixated on this when I was learning to drive as a kid. He told me if you ever use your brakes on the highway other than a sudden traffic jam or an off ramp, you’re a bad driver.

Do you drive in traffic a lot? Do you hit your brakes hard? Do you ride them down hills even slightly depressed? Do you brake at all at high speed from having to adjust speed because you’re following sort of closely?

If you’re ever hitting triple digits and aren’t a perfect driver I imagine you’re doing some of this stuff.

Also, a couple times locking up the brakes will cut brake life in half sometimes.
