No. 1. - Don't Drink and Pump!
Recently we've learned about Kim's rather interesting priorities when it comes to car safety. On the one hand, everyone (including wigs) should always be buckled up. However as long as you have someone who can man the steering wheel while you pump your breasts, there's no reason you shouldn't save some time and fill up bottles on your way to run errands. I guess that's one way for Brielle to practice her driving.
