Quite right, which is why I'm positive that you never drive: with a live passenger; with the radio on; while operating the windows, heat/ac, cruise control, or any other switches, dials, or gauges in the car. You also should never drive on anything less than 8 hours of sleep, as numerous studies have shown that your mental abilities and reaction times rapidly diminish with even minor sleep loss. It goes without saying that you shouldn't be on any medication whatsoever.
Should we keep going? I can play this game all day long.
