BABY ON BOARD signs

[AFTT47]

IDK, I think you may be thinking too hard.  A baby on board sign is more likely to be a "please don't hit me" than some sort of exhortation to hit someone else or an elaborate comment on the relative value of life based on age.

Well right but where is the justification for giving them special consideration for not hitting them vs. hitting someone else not having a baby in the vehicle? Why should anyone get such special treatment?

Hell, I would be more favorably inclined to a sign which said, "Young, Hot Blonde with Great Legs Onboard!."

But I would not be so arrogant as to make a case that someone should go out of their way to specifically avoid hitting my vehicle because my preferred form of life was onboard.
