Everything you say may be true, but I fail to see how it justifies speeding through someone else's residential neighbourhood. I generally have a healthy disregard for speed limits but in residential subdivisions you'll generally find me driving well below the defacto (not posted) speed limit of 50 km/h (30 mph).
Driving through neighborhoods is not ideal. You can get stuck behind someone who is not in a hurry. But after being stuck in stop and go traffic jams for the Nth time I finally got fed up and mapped my way through the neighborhoods.
Unfortunately real estate development is like immigration. Once you open up the floodgates the new people have no sense of what things were like before they got there(room in the schools, low taxes, roads to drive to work) , so they support even more, no matter what the cost or effects.
