Oil changes are pretty much the least costly part of my car's maintenance. Brakes, suspension and tyres cost far more and I can't imagine that heavy EVs are any better on any of those.
No less than with a manual transmission car. I went 5 years before replacing the pads on my last car, with 150k km driven—not because they were worn, but because they were falling apart.
I haven't driven an EV yet, but from what I hear regenerative breaking is much stronger than engine breaking with a manual car and can essentially bring the car to a stop in city traffic.
I drive a diesel. Back when I had a regular freeway commute, I would regularly come to a complete stop at the end of freeway exits without touching the brake pedal, just for fun (last few km/h I used the handbrake). And one time when I was randomly pushing a little too hard on the brake pedal when I was parked, I burst a brake line somehow, and I ended up driving 20+ miles to my mechanic on busy city streets with no brakes, safely.
I doubt regenerative braking is any stronger than that.
