I know this is a meme and it’s meant to be silly, but there is a general misunderstanding of what the “baby on board” sign means.

It’s not “don’t hit my car with your car because there’s a baby” because you shouldn’t intentionally hit anyone’s car with your car…

It’s a warning to others that you may be distracted by a baby and do stupid shit, so maybe give some extra space and try to be understanding.
