I think they’re fine, but ONLY if you change them each time you drive, to accurately reflect the number and ages and genders of your vehicle’s occupants.
That way if your car goes into the river, the hero can swim around to your back bumper and immediately know how many trips to make to rescue everybody! 
I picked the pedophile one. I’ve given up trying to rationally explain to people that there aren’t pedophiles around every corner. Now I’m all for just increasing the hysteria so I can profit off selling pedophile-repellent and the like. If stupidity can’t be eradicated, I don’t understand why it can’t make me rich!
This is the kind of advance thinking that can turn stupid into occasionally useful. Good Job.
I’m not one of those who think the pedos will get kids because of this, but here’s how it could happen. If the pedo follows the car, sees the kid get dropped off somewhere, he could pounce knowing all that info.
I’m not saying it would for sure happen, but it could be that the kid is not with the parents. School, drop off at a friend’s house, the park, etc.
I saw one with a name, maybe…it had dad, mom, and three little ones with
THE DANG FAMILY
underneath.
I do live in an area with a high number of Asians so I’m not sure if it was a name or a sentiment.
I went to school with a guy who’s last name was Blob. Fortunately he was quite thin.
Anyway, a friend of mine was at his family’s house for some reason, and said the place was decked out with personalized country kitsch crap. Like a plaque that said:
“BLOB
Established 1965”
She said the whole thing was quite surreal.
Sounds like the Blobs would totally love these stickers. Could you imagine a minivan with “The Blob Family” emblazoned on the back? People would be constantly trying to drive up beside them and peek in the window to see how blobby they were.
“I pulled you over because you were attempting to pass where there was no passing lane.”
“Sorry officer. But I wasn’t trying to pass. See, the car said “The Blob Family” in big letters on the back. I just HAD to take a look.”
:: pause :: “Well, okay. Just don’t do it again.”
:: speeds off to find The Blob Family and pull them over so he can take a look ::
