I find EB seems to concentrate the helicopter parents - I don't know anyone IRL who is half as neurotic as some people on here. All my friends leave babies/kids in the car when getting petrol, as do most of the parents I see in petrol stations. (As an example).
We live across the road from the school, and I see lots of kids walking and riding their bikes without parents hovering behind.
I think there is a general heightened fear of the things that can happen to our kids, but I try not to let it get out of hand. Otherwise I would never go out in the car, just in case.
The older my kids get, the more I relax. (They are 5 and 6). But the more I am quietly freaking out about their teenage years. I jsut hope I grow up enough to be ready for it, as I'm sure they will.
