There is a stop sign in front of my house and probably around 95% of cars stop, and the amount of cars that completely ignore it (ie don't even slow down) is easily <1%. I think this is just more of an issue with local cultural norms.

There was some discussion amongst my neighbors about a sign near us and we found that the key variable is the speed at which one considers a vehicle to be "stopped". Some folks felt that a 6 mph (10 kph) rolling stop at an empty intersection counted as a stop while others felt that anything more than 1 mph (1.6 kph) meant that the driver was running the stop sign. Since the majority of drivers fell somewhere in that range the estimates for how many people stopped were wildly different.
