Being a new transplant to Atlanta, what the hell? The speed limits are plenty high, but that doesn't stop a rolling roadblock of 7 cars wide on I-85 going 55mph in a 70 zone...
The related issue here is a common problem in Atlanta. Residents of huge residential developments complain about traffic cutting through their neighborhood. The problem is that their neighborhood was designed without traffic flow around and through in in mind so they didn't provide any arterial or feeder roads and expect all the cars to go around the multi-square-mile development onto the existing arterial streets that are parking lots.
They protest the cars going through their neighborhood and put up unnecessary stop signs and speedbumbs to discourage drivers. But this just slows them down and pack the residential streets into a slow moving parking lot as well. Does this make things safer for kids? No. Does this make things better for residents? No. The solution is to sacrifice some "residential" streets and upgrade them to higher speed through streets and allow the traffic to get where it's going, Impeding them just makes them angry, impatient, and distracted which doesn't help anybody.
Plus I drive a small, low car and speedbumps are the bane of my existence. I hate anyone who thinks they are a good solution anywhere.
