When rotors warp there is a single answer as to why. They were not designed/manufactured thick enough. Don't blame driving styles or any bullshit like that. Brake rotors should be able to glow red and still not warp.
Worse still, with the regenerative braking system there the rotors shouldn't even need to be as high-spec as those in comparable sports cars.
And that is why there is an issue. Regenerative breaking does not help much when you do a panic stop on the highway from 65 MPH. A smaller sized rotor would be easier to warp in that scenario.
