When everyone has EVs the sound of any IC is going to become increasingly noticeable. I can see a point where IC vehicles are banned from cities on noise grounds alone.
When 99.99% of cars are EV the common man will not care about the rare ICE car that comes along anymore than he cares when he sees the DPW driving a backhoe down the street.
By the time the long tail of "people driving old junk" is narrow enough for banning ICEs to be politically palatable the bulk of the people screeching about it now will have picked up some more pressing issue and be caring about that instead.
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.
