I just get in the door at home from my bike ride home, and my wife calls me from her cell while she's driving. Usually this is the point in our conversation where I tell her it's unsafe to drive and talk, followed by me hanging up on her. But this time she says, "I called you to keep me awake so I don't fall asleep at the wheel.". I tell her to pull over immediately and either call a cab or sleep. She tells me she can't because she'll block traffic, and that it's unsafe to do so. So I decided to talk to her for awhile and preach about how the most unsafe driving practice I can think of is driving while talking on the cell phone coupled with being drowsy.
What would you have done?
