I think they see things below the bumper or rear window view. Still, I suspect that these gizmos will have no “statistically significant” effect on automobile backing accidents. If fact, I would not be surprised if they actually increase. People will compensate by becoming even more careless. There are good studies that indicate air bags definitely do not save lives: people with air bags tend to drive more recklessly. It sounds like a waste of money driven by people who want to sell back up cameras.

Remember when you could order a car with any of 7 motor transmission choices. The windows cranked down and you had rubber mats on the floor. When you opened the hood you couls see the ground beneath and all of the spark plugs?
Today you can get you choice of colors.
Todays cars are so loaded up with crap and garbage that they cost a ton of money.
Heated seats, tv on the back of the seats, electric mirrors.
Take me back to the old basic automobile.One that I can afford.
I drive through a heavily wooded area frequently, posted speed limit 35 mph. Cars rarely do 35 or more. I drive about 25. Deer are very thick there and sure I have insurance but don't relish the thought of getting smacked in the face by an air bag.
