Like I said in my post, I've driven slowly, and the kids come flying out of the driveway and hit me.
When I was a kid, we played on the residential streets, rode our bikes all over, even flew model planes over the streets. It was expected, because there were a lot of kids, few if any playgrounds, and back yards were small.
That, and people cared for kids back then - anybody's kids. Toddlers are fast-moving and their judgement meters haven't been installed yet, so slow way the heck down, and watch hard for any movement out of the corners of your eyes in the residential streets where kids live. It's part of our responsibilities as drivers.
Just this evening, coming back from class, I had a 2-3 year old little boy in the middle of the street in front of my car. I came to a stop and waited for his dad, who ran quickly to get him.
Kids are important. Witless, but important.
