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. has been delayed.

I prefer sensors alone over a rear view camera as I can reverse normally checking my mirrors and all around the car while listening for the beeps


Absolutely, you can look over your shoulder like you always have with a much larger field of view than the camera gives you. The beeps are just to warn you of something you missed or to help you back up to within a foot of whatever your backing up against. I used both all the time when I worked at a Nissan dealership and much preferred the beeps.

PS you should not be relying on mirrors either when backing up, swing your head around.

You obviously weren't paying attention to the article:

Field of view from your drivers seat doesn't do you much good when the tailgate is blocking your line of sight to smaller objects.

The fatalaties are sad, but realistically they're rare enough to probably not be worth a mandate at this point. I'm curious what kind of collision/property damage would get averted, though. I wouldn't be surprised if we had tens of millions of fender benders per year due to backing up.

Right that's what the sensors are for, if something is behind your car they beep. Trust me I cant see anything under probably under 4 feet when I'm backing up.
