A bit all over the place. For one, they linked it directly with weight. But then they mentioned regen and decided to model it at 0 brake wear on EVs. Then they talked about EVs being made of lightweight materials such as aluminum, and the difference would be even larger if they WEREN'T. (what?)
It also models particular resuspension in the air as a function of vehicle weight, arguing that heavier vehicles are typically less aerodynamic -- which is probably not the case with EVs.
