Yeah but that doesn't really motivate saying "its newly purchased EVs are twice as expensive to fix as its gas cars." Any reasonable interpretation of that is that they are much more expensive to repair for the same damage, or service for the same service interval/distance driven, or similar. If "it's twice as expensive to maintain the cars that are driven twice as much" then that would be exactly what's expected and not be an argument for buying less EVs at all?
