Most of the streets in the city I live in are 40mph(64kmh) zones. With the short distance in between stop lights, by the time you reach 40mph, it's time to stop for the red light. People over here are in a constant state of hurry. If they can get to 50mph(80kmh) before the light turns red, they will do so. They are always waiting at the red light before I get there since I drive 35mph(56kmh) most of the time. Why so slow you ask? Because the way I see it, the faster you drive between red lights, the longer you have to wait at the red light when you get there. Am I wrong to drive 5mph(8.5kmh) below the speed limit? I just don't see the point in driving the speed limit, or 5-10mph(8.5-17kmh) above the speed limit, since you have to slam on your brakes when you get to the red light anyway.
