“Baby on Board” - the sense of entitlement cracks me up! I wonder how many people know the real reason for having these signs - they’re not to deter tailgaters! They’re meant so that if your car is in a serious accident, that emergency workers search around your car incase an improperly secured car seat (or baby within one) has been ejected from the vehicle. They should always be taken down when the baby is not “on board”.
