Yes but considering the total length of paved roads in the world, often using asphalt, how they stretch terrain from coast to coast, on all inhabited continents, that some of it will pass areas that will be uplifted and brought to daylight - I see it as inevitable. It might need a trained eye to see, but it would be there.
Maybe. The surface area of all the roads in the US is ~25k mi2. Which is ~0.6% of the surface area of the whole US. And the US is a pretty advanced country in terms of road density and variety. I think we can say that the total global road density is likely less than even that. Now sure, road density isn't randomly distributed across the surface of the Earth. But future people will still need to get lucky just to see roads at all.
