The EV motor is all contained in one unit, so no maintenance is needed, of course you need to check brakes steering etc, but if you use Re-Gen braking then you will hardly use your brakes so less wear on the pads.
Brake fluid is hygroscopic, needs to be replaced every 2 years. Cabin air filter same, ditto HEPA filter, A/C desiccant bag, etc just because they have an electric motor doesn't mean no maintenance.
the BYD i test drove didn't come to a complete stop, but it was close, i hardly touched the brake.
Doesn't matter, brakes need servicing even if brake pads don't need replacing. FWIW the BYD is probably the worst EV for one pedal driving.
the only issue i had was sticking to the speed limit, they are so damn quiet you speed without even noticing
EV's are only quieter than ICEV's when accelerating and even then up to around 60 kph, much over that the tyre, road and wind noise drowns out the ICE anyway. Try it with a noise meter, I won $100 off a Tesla owner when his Model Y was 3db louder at 90 kph than one of my twin turbos.
