There are literally hundreds of sources you could find for how EVs have worse wear.
I have no idea what you're on about with "chatter" without specifying any specific part of a drivetrain...
Like your whole comment reads like someone trying to apply extremely general theoretical concern while handwaving away actually connecting it to practical application...
And where are you getting the idea that:
a) the weight difference will only be 150kg. These things can end up doing 50 miles with a heavily loaded truck in high heat. They'll need the same cooling systems the ICE does, they'll need battery packs over-provisioned to meet their 25 year life span mandate.
b) even 150kg wouldn't increase weight. I don't know what you think "designed in" means. It means either make the parts beefier so that they can withstand greater wear before replacement, or it means replace parts more... neither option erases the problem.
ICE or EV obviously they're going to design the suspension to handle the curb weight + occupants and cargo but adding to the curb weight will have the result of making something more expensive. Doesn't really matter if you're paying for it upfront or later, you're paying for it.
My Spec Miata's suspension alignment was designed with my weight in mind and literally every pound counts. Even the weight of the gas in the tank opposite me can have a noticeable effect on how the suspension sits, which in turn affects tires wear.
The same thing plays out on a "normal" car in much slower motion
My comment only addressed wear on components, and specifically mentioned tyres and ball joints. I am not making a statement on upfront costs. I’m also not considering behavioural changes of users when switching to electric motors.
