I agree with this, I have 3 kids, age 30, 29 and 17. The 2 eldest played in the road on front of our house with all the neighbourhood kids ......but that was 20 years ago....probably only about 8 people in our street owned cars then, and it was a quiet side road that wasn't used as the school rat run.
My youngest has never 'played out', kids dont do that anymore (unless you count the feral kids around the corner that are abandoned onto the street in the summer holidays), they sit in their rooms on their laptops/iPhones/Xboxes. The road is way to dangerous for them to be out playing kerby now, to many cars, driving to fast fir a side Rd, and around what is now a blind bend.
