Not going to happen in 50 years, probably more. I still see a lot of >20 yo cars, lots of people simply can't afford a new or even used car. Let alone trucks: my father was a concrete mixer truck owner (sorry I don't know exact word for that), when fully loaded the truck run 300 meters with one liters of diesel, it's more than 30 liters per 100kms.
