I think it is a great idea to keep a camera in the car at all times to document any accident I may be involved in. This happened to my son near my house and I was able to go to the scene and photograph it before the cars were allowed to move. It proved to be invaluable. This convinced me that I should buy a cheap camera and keep it in my car at all times. However, I wonder about the extreme temperatures that a car in the Mid Atlantic states would be subjected to. I doubt that conventional film could survive summer heat and winter cold. What about a digital camera? Can they survive the temperature extremes? I would want one with a flash and at least 2 megapixels.
