I think it's genius. I don't know why it's not advertised.
A car babysitter solves almost every errand-running problem known to the modern mother. Need to run errands with the kids in the pouring rain? Not looking forward to hustling multiple children in and out of stores? Does only ONE child need to go to the bathroom during that necessary pit stop!? Do you need to dash into the post office for only just a second, or into the grocery store for a single loaf of bread? Behold, the glory of the Car Babysitter!
For the price of one Starbuck's beverage of their choice and $5 of cold hard cash, you can enjoy the company and convenience of the Car Babysitter for an hour or so. She'll sit in the passenger seat of your car and talk to you as you drive around town. With luck, she'll be a witty and engaging personality. She'll entertain the children and stand guard over them as you waltz in and out of stores with ease and precision. (And even if she is as dull as a doorknob, the chances are she can still successfully occupy a passenger seat and make sure that no hard comes to the children in your momentary absences from the vehicle.)
The modern mother would be able to run errands about 62.344% faster by employing a Car Babysitter.
Almost 97% satisfaction guaranteed success! (The variables being the State of the Children during errand running and the wit of the Car Babysitter.)
I just made this up as far as I know but I think someone could make themselves a boatload of money out of marketing themselves to mothers this way. *I* would pay for a Car Babysitter. In the meantime, I just assume that one day my oldest will function in this capacity and that will indeed be a glorious day.
