As a person without children, and whose friends mostly don’t have children, I have only very limited knowledge of where the schools are, much less what each one is called.
Just because I don’t have my own kid, doesn’t mean I want to be the douche who runs over someone else’s. So I pay attention to the School Zone signs (and yield signs, and stop signs, and other things you should be noticing while driving.) I know I p’d a whole line of people off by rolling down 35th at 20MPH in a school zone last week when I saw kids around. Tough.
People need to slow the F down in general. If you are paying attention to the road and not texting or chatting on your phone, you’ll almost always see the signs.
