Please describe the most comfortable way to sleep in the car?

Interesting Question: Beware sleeping in a car can be dangerous. Never sleep in a car where the exhaust pipe might be blocked, i.e. In a snow drift. Make sure your car is off the roadway and out of traffic. Do not sleep with the windows closed on a hot day. Have a blanket available in cold weather. Other than these warnings, the size of the car and the size of the body determine the level of comfort.
