cars go on it like 30 km/h cause it's so narrow. No need for any infrastructure.
If the road is wide enough for cars to go faster - it's wide enough to fit pavement (one side at least). Pavement can be very narrow too - 1 m is infinitely better than no pavement. I've even seen 0.5 m pavements but that's stretching it :)
If the road is so narrow you can't fit pavement there - it's probably safe already.
But I've seen roads in USA and I think you just have no comparison on what "no space" means.
