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).
