Why have a Baby on Board sign in your car?
Do people think it creates a protective force field around their cars?
Will other drivers really think "well I was going to crash into you but now I can see you have children, I won't"?
I have heard the argument that they are there in the event of a crash to warn emergency services to look for a child but people don't take the stickers out of their cars when the kids aren't in it, do they?
Isn't the child car seat larger and more conspicuous any way?
Really don't see the point.
