You can get similar results with proper deceleration, engine braking and downshifting. I’ve had brake pads last 110k miles (with room for 20k+ more), even though I lived in moderate hilly area. That’s probably 1/3 the brake dust, and comparable to an EV .

If you are getting lower MPG than the EPA rating, you are also burning up your brakes from heavy deceleration. Improve your MPG to 15% over EPA and your brakes will last a lot longer.

Also their studies were in European markets with tiny EVs and low speeds. Americans are favoring 7k-9k lb EVs (Hummer, Rivian), with massive brake rotors and PADs— at highway speeds 75mph+. A good driver of a 3k lb vehicle will produce less brake dust than a typical driver of a 9k EV.

Studies like this are helpful, but they are not comprehensive. Similar to the marketing that home LEDs would have 10-20 year longevity, yet in practice they burn out after a few years. The full supply and application chain has to align for the ideal results in practice.
