bumper stickers on board

What exactly is the point of putting a sticker on the rear windshield of a car that says Baby on Board? Is it presumed that someone behind this car will be considering rear ending the car for the fun of it, but then they read the sticker and go, “oh no I don’t want to hurt someone’s baby.” That sticker has zero effect on me. Maybe it’s because I don’t know this baby so he must not be that significant to begin with. If I saw a sticker that said I was on board, despite being confused about how I could be in two places at once, I would probably do my best to avoid accidentally hitting that car in an accident situation. Or if the sticker said “baby tiger on board” because they’re endangered. Human babies are abundant.

I recently debated with myself over purchasing a bumper sticker that read, “Question Consumption.” I thought it would be ironic to frivolously spend $5 on this sticker, but I ended up buying it because I realized that I had in the purchasing of the bumper sticker in fact questioned consumption, and everyone knows that honesty is important when it comes to tacky car adornments.
