Most moms are cautious drivers unless they are running late. When it comes to getting their precious cargo to school before the bell, lots of women put the pedal to the metal so their kids aren't tardy. Last night on Parenthood, Julia and Sydney's quality time in the car was interrupted when another mom and tot cut them off in the carpool lane. The situation had working mama Julia, who was already in a rush, fuming. Do you ever find yourself becoming a bit of a road warrior or getting an attitude in these types of situations?
