Compare Backup Sensors & Cameras to ParkFX for the Most Reliable Backup Warning Technology

Not all reversing aids are equal. The sensing technology and the indicating method are critical to your driving safety.

How A Park Assist System Alerts You

One option is video, which at first seems like a great choice. But one major flaw with having a video camera affixed to the back of your car with a monitor on your dashboard is that it also forces you to look forward while backing up. That can disturb your perception, your reaction time, and feel very unnatural. They are also extremely expensive, and you'll pay thousands of dollars to have a video system attached to your car, whether from the dealer or an aftermarket supplier.

Compare that to other bargain basement devices which actually have LED displays (little red lights) on your dashboard. These are cumbersome -- almost useless -- for much the same reason as video: when you drive in reverse, you naturally look behind you, and you'll never see the little red lights. They are also hard to read in bright sunlight.

Some other bargain technologies use a tone which beeps more rapidly as you get closer to an obstacle. You can at least hear the relative distance just by listening to the beeps, but you have to practice a bit to really understand how far you are from danger.

That's why an audible voice sensor is best. It tells you in a spoken voice exactly how far away you are. Not only do you not have to awkwardly look forward at your dashboard, you'll know without guessing how much further you can safely back up.

How A Reversing Aid Detects Objects

If you've never seen or used a reversing aid, you might be surprised at how technically advanced they actually can be.

Reversing aids use a variety of technologies to sense an object behind the car. Some units use Doppler radar, and others use infrared sensors, but by far the most accurate method of detection is the one the U.S. Navy uses on its submarines: sonar.

Sonar can operate in any weather, including direct sunlight or rain. And it doesn't require that the car be moving in order to sense an obstruction.

ParkFX is the 360-Degree Backup Solution and it's Less Costly Than Backup Sensors, Park Assist and Rearview Cameras

Deaths increase. Ninety-one children were killed in 2003 by drivers who didn’t see them while backing up, according to Kids and Cars ( www.kidsandcars.org ), a nonprofit organization working to improve child safety around vehicles. Those deaths represented a 57 percent increase from 2002. During the first six months of 2004, more than 40 deaths have been attributed to backover accidents, many involving vehicles with large blind spots.

Kids and Cars compiles these statistics; the federal government does not track such incidents. Janette Fennell, president of the organization, believes that backover accidents are underreported and that the actual number of children killed or injured is much higher.

Blind spots grow with vehicle size. A likely reason for the increase in injuries is that minivans, pickups, and SUVs account for more than half of all vehicles sold. Many have large rear-view blind spots.

Last year, Consumer Reports began measuring the blind spot of each vehicle we test, checking the distance for short drivers (5 feet 1 inch tall) and for those of average height (5 feet 8 inches tall). The biggest blind spot: 51 feet for a short driver in a Chevrolet Avalanche pickup. But even small sedans can have blind spots of more than 40 feet. We regularly update vehicle blind-spot information, which is available on this site free of charge in The problem of blind spots.

Systems other than ParkFX combine a camera with sensors, so we tested each system independently; it is listed with camera systems in the Ratings.

All the systems we tested are potentially useful. They’re a good complement to looking around the vehicle before entering, and checking the rear window and rear-view mirror just before and while moving in reverse.

Device Reads Email Messages to Drivers

Tech Digest reports on a new gadget and speech recognition system called iLane that provides drivers with a hands-free way of listening to email messages. iLane can also handle phone calls, calendar requests and SMS messages. The device plugs into the cigarette lighter.

iLane is a small device that interacts directly with existing Bluetooth-enabled handheld devices, allowing drivers to fully access their email in transit. iLane notifies the driver of incoming emails and other important information by reading a brief summary in a "natural sounding voice". The driver can then listen to the entire email message; forward or compose a response using verbal instructions. Phone calls, SMS messages, and a number of email attachment types can also be managed. In addition, filters can also be set to priorities mail, so you don't get hassled with that latest sales pitch from an online store.

Better than some automakers "detectors"

LaneFX actually shows you what's lurking in your blind spot!

LaneFX is More Than Just a Car Gadget

Many of the latest car models include systems that alert you when a car is in your blind spot. Those of us with older autos have had rely on our own road skills -- until now. Drivaware has introduced LaneFX: When you activate your turn signal, the device moves the corresponding side-view mirror to expose your blind spot and any vehicles that may be hiding in it. Of course, if you remember your driver's training, a quick glance over your shoulder does essentially the same thing. The LaneFX is compatible with any car that has power mirrors and is available in a Basic Edition ($197), Highway Edition ($242) and Commuter Edition ($296).
