My such pessimism. Come see in 20-30 years. There’s no doubt that we will still be using some form of hydrocarbon fuel for transport (aerospace comes to mind) but the slice of oil is going to shrink and shrink. The plastics you speak of are there because the oil sludge by product that plastics is made from is there and essentially a “free” by product of our energy cycle. It won’t go away, but I wouldn’t be surprised to see it largely displaced by more modern materials and materials science.

The point isn’t that oil trucks will go away entirely, it’s that they will become much less common, just as Ice trucks are today.
