I live in the US. Near my house inside a residential area is an uncontrolled intersection (an intersection with no signs and no defined right-of-way). I always slow down when crossing it (the posted speed limit is 15 mph), but not everyone does. It's scary. When visibility is low, I avoid the intersection. I plan on petitioning the city to put up a pair of stop signs to make that intersection safer. For the small amount of money these towns will save, their residents will incur huge increases in insurance (auto and health), travel time and accidents, and stress (imagine being scared at every intersection), and decreases in tourism (tour books will tell visitors to avoid those places) and safety. This is absolutely the worst idea in civil engineering I've heard in a long time. Road signs are necessary to safe transportation. Absurd.
