Gas vehicles have complex combustion engines, transmissions, differentials, emission systems all of which require maintenance and can leak fluids that are expensive to fix. All of which are common points of failure. Everyone I know owns a car and all of their cars have had problems with one or more of these systems. These are all facts that are common knowledge and don’t need any supporting evidence.
EVs have 1 common point of failure. The battery. That’s because there isn’t anything else to break on them. They’re simple and durable.
