If you understand “car” as “hardware degradation” there is something to it, despite calling it “electromigration”.
You said it (= whiskers) can be simulated and that it’s called electromigration. From what I understood, this statement is wrong, since they are both different in both cause and effect. Metal whiskering can be simulated to a certain extent, yes. But that’s vastly different to what electromigration is and how it works.
