I'll be the first to admit, I don't typically speed on surface streets, and you should see the ruckus I often cause by slowing to 25mph in school zones, but...

I decide how fast I drive, not a sign by the side of the road. If there are others about, either in vehicle, on foot, or on bikes, I drive accordingly. Most of the time, it happens to be around the posted limit, sometimes higher, sometimes lower, but generally around the limit. However, if I was on a city street during a slack time and I opted to drive faster, and a camera caught me doing so, so the next day my face and name were posted somewhere public with the info that I was doing 47mph in a 30mph zone... Why would I feel shame? What about this would cause me to change my future behavior? Basically, so what?
