There's a stop sign near my house that is often ignored and when I watch people blow through it (while obviously speeding) I wonder how much fear for letting our children wander is reinforced by behavior like that and how a lack of children playing reinforces that behavior. As far as speeding goes, I generally stick to the limit in a residential but when I'm being tailgated I'll speed up to 30mph. I'd rather only have to worry about stopping the force of my vehicle if a child runs out in front of my car. But it rarely makes a difference, most people want to go 40-45mph and become visibly irate at anything less than that. Things like that make me happy that self driving cars are somewhere on the horizon.
