Safe Driving with a Lively Backseat

QUIZ QUESTION: Which one is the greatest menace behind the wheel?

1) A college student driving a Beemer while simultaneously listening to her Ipod, Facebooking on her Blackberry, laughing on her cellphone, sipping a $12 Starbucks drink and applying mascara

2) A blind and deaf 85 year old driving out of the church parking lot

3) A 16 year old test-driving his uncle’s red Ferrari while test-drinking his grandfather’s homemade whiskey

4) An overworked, underloved 55 year old banker gunning his new Harley past the playground where the pretty moms hang

5) Me, behind the wheel of a Camry, with Angelina screaming loudly enough to shatter the windshield (she strongly dislikes car rides), Bean incessantly requesting fresh-squeezed orange juice, Bella insisting that I talk like Peter Pan while she pretends to be Wendy Darling, and our slightly-too-peppy Fisher Price Car Songs CD in the background.

The correct answer is (5). I won’t describe the three “thank you guardian angels” near-incidents that I’ve created in the past two months. Suffice it to say we’re basically entirely pedestrian these days (thanks to the great, walkable village where we live) until I get the situation under control. Do you have any suggestions on car rules/guidelines for lively little passengers and ways to enforce rules while driving? Or should we go ahead and install an automated sound-proof window that separates the front seat from the rest of the vehicle in our Toyota limousine?
