@KBear, I disagree with your opinion that the route drivers use isn’t important or an issue. With the proliferation of various driving apps (Waze etc) residential streets are getting congested in ways that were never intended by city planners and traffic engineers. We shouldn’t be using residential streets as thoroughfares for automobile traffic (Note: this is not relevant to bicycle traffic). We as a city are already reacting to this by introducing varying methods of traffic calming. Such as this in my old stomping grounds:

The city could have diverted those resources to more important projects if only its citizens would use a little common decency and understanding of why we direct traffic through arterials etc.
As to the OP, children should be supervised whenever they are in a roadway or close proximity and posting signage which can be helpful does not negate their responsibility. Signage should not be put physically in a roadway to cause an obstruction. We already have processes in place to request speed humps etc. We all have to share the road and that means we all take responsibility for our own safety and the safety of others. It only works when we all follow the rules. I also recommend getting a dashcam for your vehicle.
