>Why are you assuming that traffic is moving at 30-45 mph through a neighborhood.

Because that's what I see in the suburbs here in DC.

>In my neighborhood the speed limit is universally 25 and the stop signs & one way streets keep traffic speeds down.

Those aren't typical American suburbs if there's 1-way streets. That sounds much more urban in fact. The suburbs I typically see have wide streets, and 35mph speed limits, and people driving around quite a bit faster than that in their huge luxury SUVs. I also don't see kids in the streets at all, and for good reason: it's too dangerous. I don't feel safe at all on my bike, even though I ride very fast and as far right as I can (I only ride in the subdivision near me so I can get to the multi-use trail on the other side).
