Seriously, the nazis were able to compile lists of political enemies (suspected to be) in Brtiain 85 years ago.
It’s not a stretch to suggest the US knows exactly who is relevant to keeping the regime alive, whom to imprison and whom to kill.

Rough tiled surfaces are noisy though. It would be pretty annoying if you live next to such a road if there is more than a homeopathic amount of car traffic.
That’s not to say having a 4-lane highway in front of your door would be any better. Just that rough tiling isn’t ideal for noise (even when adjusted to the lowered speed).
