yabu, sorry but we bought our house EXACTLY because its a very quiet cul de sac, no through traffic and perfect for the kids to play out, our children and all the others in our cul de sac, so 3 from across the road, a few from the flats at the end and 4 from next door, plus mine! all play out and its great.
we all set boundaries ie there is a lampost they cant go past so they dont go near the turn in to the cul de sac (but that road is a 20 mile limit and anyone that does turn in is going very slowly anyway due to the angle)
various parents are often sitting out and i can see the children from my sitting room and kitchen windows.
IF there are a lot of parked cars, i say no ball games, or stay in our front garden rather than in the cul de sac. but the kids have all played out since old enough ie 4-5yrs and they have a great time, its really nice.
I ended up with my neighbours grandchild in my front garden this morning as he wanted to come and play with my dd, he is just visiting for a bit and it was lovely that he could play out, he had a great time on my boys tractor riding about!
i have to say i do worry re noise, i tell my kids not screaching/shouting but they are children and so there will be noise, i wont let them out till 9am on a wkend or bank holiday etc but it is soo nice to be able to let my children play out :)
