>Every single residential street in America...

Even the largely carless (read: not many cars parked on the street) ones like my neighborhood that had a whole bunch of kids happily playing outside and in the street this weekend without issue? Every single one?

The street directly in front of my house is largely like that. I don't even feel very safe doing the edging standing in the street, people turn down the street off the 40MPH (probably going 45-50MPH) main road next to it and blindly start heading down the residential street at 25-30mph.

The cul-de-sac behind my house through the alley is a good bit calmer. That's where my kids go to play.
