IIHS Says Rearview Cameras Alone More Effective than Cameras/Sensors Combined

Cameras alone are more effective than cameras and parking sensors says survey
Rear view cameras are becoming a standard accessory on many cars sold in the U.S. The cameras have been mandated to prevent accidents where
small children are backed over by inattentive drivers
The Insurance Institute for Highway Safety (IIHS) has performed a study -- using volunteers driving 21 different vehicles in an empty parking lot -- that found backup cameras are much more effective than parking sensors while travelling in reverse.
The results of the study show that cameras would better prevent “backover” crashes into pedestrians who are in the vehicle blind spot than parking sensors alone. Oddly, the study found that while cameras worked better than sensors alone, the camera alone worked better than a combination of sensors and camera.
"Right now cameras appear to be the most promising technology for addressing this particularly tragic type of crash, which frequently claims the lives of young children in the driveways of their own homes," says David Zuby, the Institute's executive vice president and chief research officer.
During testing, researchers used a pole that had bands painted to represent children of different heights. Bands were market for the average height of children 12-15 months old, 2.5-3 years old, and 5-6 years old.
The study found that on average if the child was within about 27-feet of the back bumper, drivers couldn't see them using mirrors and looking around alone. Not surprisingly, large SUVs performed the worst in visibility, while small cars typically performed the best.
An estimated 292 people die each year and 18,000 are injured by drivers that back into them. Backup cameras reduce the rear blind zone by 90% on average according to the study.
Current legislation that would mandate the installation of backup cameras on all new passenger vehicles sold in the U.S.

YOU don't NEED to have small kids. That pre-supposes that NONE of your friends have small kids either (or that whenever you get together, it's either always at your place, or it's in a public setting).
By your logic, NONE of the safety technologies should be in your car. So in other words, your ideal car would be like a 1959 Chevy Bel Air.
Seatbelts? Don't need 'em. Airbags? Yank 'em. Turn signals? Yeah...you probably don't use those either. Crush cans? Pull 'em. Crumple zones? pffttt...I LAUGH at you.
If you crash into a tree or a building, that your problem. Where it becomes a public problem is when you crash into someone ELSE, (or someone else crashing into you), and then because YOU have NONE of those things, your risk of injury is SUBSTANTIALLY and SIGNIFICANTLY higher, which means at best, you end up in a fair amount of pain, but you get a big fat check for it or you end up being paralyzed for life, leeching off the government for the rest of your vegetative life.

People, generally and for the most part, SUCK at math, arithmetic, and statistics. They don't understand it, and then WE end up having to pay for your "lazy pro-socialist" butt because you won't buy a car that has been properly engineered to mitigate your risk to society. So instead of forking out a hundred to two hundred bucks for the camera, we have to pay THOUSANDS to keep you alive with a breathing machine because you now have a collapsed lung after being ran over by a truck that was backing up.
