Addendum to car window Garfields:
We're never advised as to whether or not babies are on board anymore. I like to made aware of baby/boarding status when I'm driving. If there's a baby on board, I'm going to watch my language and follow the rules of traffic safety. If there's not a baby on board, I'm going to be driving like a bad out of fuckin' hell. I've been driving like there are no babies on board but maybe it's just a breakdown in the baby-on-board infrastructure. I can't believe I haven't killed some kids yet.
It's very possible this bit was done by somebody back in the baby-on-board days.
