Obviously not knowledgeable on cars. Who’s going to rotate your tires, replace a worn out suspension, etc etc.? More importantly who is going to insure all the electronic and safety systems are operating correctly. Just think of today’s annual smog and safety checks required in today’s vehicles. These will be replaced by frequent safety inspections assuring autonomous vehicles are operating safely. And how about the very limited life of batteries? There is no miracle cure for that yet — an expense you ignored.
