With true one pedal driving you really only need to use the brakes for sudden braking. The car can come to a complete stop on its own when you take your foot off the accelerator, so if you planned your stop well, you don’t need the brakes. If you didn’t plan it well, then you use the brakes.
You could do entire shorter trips without using the brake.
The longer the trip the more likely something happens where you need it.
I don’t think you understand what one pedal driving means. You absolutely need to use the brakes on a regular basis.
