If you get the speed limit wrong with a sign, you can change the sign. If you get it wrong after throwing built obstacles all over it, we are stuck with it. And you're going to get it wrong sometimes, because neighborhoods and safety technology changes (and because safetyism gives low-speed-limit people too much political influence).

Some of us have children, and some of us will hopefully always going to have children, so sorry, but we won't go away with our safety concerns as death on the road is the number one safety issue in everyday life.
