|Not to mention how ridiculous you look.|
Several studies, such as a 2005 paper in the British Medical Journal, have found that talking on a cell phone, even with a hands-free device, causes more driver impairment than a 0.08 BAC.

And then there is having a baby in the front seat, safely protecting you from a collision with the steering wheel and the airbag. Of course the airbag will kill your kid when it impacts his face at >100 mph. (There's the equivalent of three shotgun shell loads inside it to make it inflate fast enough.) If it doesn't inflate fast enough, then your body will crush your child through the steering wheel. Of course, that's not something that would EVER happen to our BrittBritt.
You can't fix stupid.
