Just spent 10 hours replacing a valve cover gasket, spark plugs, wires and cleaning the Fuel injection system on my son's car, V6. Made me think, why do we need all this "crap" on a car. All this maintenance, replacement parts, oil leaks, fuel injectors and pumps....also made me think how disruptive a Tesla car is to all the companies that build the "crap" that is on all the ICE cars that would no longer be required if everyone owned a tesla. How many mechanics would not have a job, no more gas stations, no more of these mickey mouse oil change quick lubes, etc. How it would change the automotive world as we know it. Seems like Serenity in the Car World had begun.....! P.S. No more grease spots in the parking lots at the mall.
