My wife and I have had this conversation before, and we are aware of the particular case you linked too. I don't want to come across as crass, but, with respect, I will make this short observation: You trust your child's life to hundreds of strangers every time you drive them somewhere. The chance of your child being hurt by a careless/bored/insane stranger on a per trip basis is very, very low. I assert that the risk of child services becoming involved after you let your child play on a trampoline (or whatever) is even less.
