Car rides are CRAZY!

I don't know what the deal is lately but, my kids have been extra LOUD and CRAZY in the car. They have yelling contest to see who can yell louder. Or else Luke is telling me to turn where he wants, climbing out of his car seat or wanting something right this second. Then when we throw Carly (my niece) into the mix it's that much crazier & louder. For sanity reasons I've been seriously pondering investing in one of those roll up window partitions they have in limos. Wouldn't that be sweet?!
