DH is very keen on us displaying a 'baby on board' sign in our rear window whenever we go out in the car with DS. He believes that drivers behind us will be much more considerate and not tailgate if they see this sign.
I think that most tailgaters don't understand why they're meant to be leaving a sensible stopping distance between them and the car in front, don't understand how their behaviour is potentially dangerous, and therefore I think that if a driver normally goes around tailgating the car in front, he's going to continue doing so whether or not there's a baby on board sign.
AIBU to think that these signs make no difference at all to other driver's behaviour?
