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.

Yay for cameras!

Seriously, why do we use mirrors in our cars anymore? We have so many blind spots, and seeing on the eye-level plane is hardly ideal in the first place. On top of that, the removal of side mirrors would improve mileage, cut down cabin noise, and look better.

Beyond all of that, cameras are cheap these days. Dirt cheap. The cameras found in our cell phones are more than good enough to get the job done in a car situation. Slap in some wire, a cheap ARM processor, and replace the instrument panel with an LCD and we are all set. It is not going to add that much weight (no more than a small laptop, minus the weight of the parts replaced), and it does not need to be expensive (except that they will find a way to make it expensive). This is something that should be a standard requirement for every car maker so that we as drivers (and our computer overlords when they start driving us in a few years) will have a much better sense of our surroundings.

Don't forget that it's possible for the camera to break, get plugged up with dirt / mud / ice / snow which means you'll always need mirrors as a backup.

Still I agree that the sensors are useful. I have ultrasonic rear sensors so I don't accidentally back into poles, cars or walls. They are very helpful in figuring out how much closer I can park my car without bumping into something. I also have a camera too which is useful for backing up but I also depend on my mirrors as well.

I would also caution people that using the cameras at night can be risky. Not many cameras have sufficient nightime sensitivity.

Yup, the new blind spot warning setups are great and should definitely be added to large commercial vehicles.

I saw an interview with Elon Musk where he complained about mirrors also. Apparently there is legislation that mandates cars have mirrors. He wanted to put cameras in his Teslas but the law requires mirrors on all cars and laws are a bitch to change. :(
