How To Avoid Car Gadgets & Choose the Right Park Assist Technology for Your Driving Safety

Know how the device mounts on your vehicle.

Camera and sensor systems that are mounted on the vehicle’s bumper or bodywork may necessitate drilling. They may not be the best choice if you lease your vehicle. If you have a hitch, you can consider a model that mounts in the trailer-hitch receiver. But you would have to remove the system to use your hitch. Other camera and sensor models mount on the license-plate frame. But some states prohibit frames because they can obscure the plate.

Within types, features vary. This is especially true with the sensor models we tested. The ultrasonic systems were generally the most sensitive, but their performance was adversely affected by rain, snow, or other inclement weather.

The microwave-based sensor systems we tested were not affected by weather but are less sensitive as a group. They also don’t warn the driver unless the vehicle or object behind it is moving.

The display quality of the camera-based models is very good, although it doesn’t match that of the larger screens on some carmakers’ systems. Most of the system displays turn on when the vehicle shifts into reverse, but one, the Audiovox, must be turned off and on manually.

More than 2,400 children are accidentally backed-up over each year in the U.S.

And of those, more than 100 die. With the proliferation of SUVs and mini-vans, drivers aren't aware of the enormous rear view blind spots that prevent them from seeing what's behind them, especially small objects, animals, people, and children. Some of these blind spots are even greater than the length of an average driveway! Senators Hillary Clinton (D-New York) and John Sununu (R-New Hampshire) have recently proposed legislation requiring the U.S. Department of Transportation to issue regulations aimed at reducing accidents that frequently kill or injure children in cars. But until that legislation is passed, it's up to the driver to protect their loved-ones and prevent a tragedy by using a Park Assist system or a backup camera.

In fact, the Centers for Disease Control and Prevention estimated 2,767 people were treated in emergency rooms from July 2000 through June 2001 because of backovers. "This is a huge problem," Fennell said. "A lot of [the problem] is due to the change in our vehicle mix" that has more people driving tall-profile vehicles, she said.

Indeed, Fennell's research indicates that "in 60 percent of the [backover] cases, it's a truck, van or SUV that's involved," Fennell said. The reduced rearward visibility is caused by the design and tall profile of SUVs, pickup trucks and even vans.

The top edge of the tailgates and liftgates in these vehicles typically sits high and so do the vehicles themselves. This means that unaware children and small-stature adults and anything not tall enough to be visible in the rear window glass might be run over as the vehicle is backing up.

Consumers can choose from a wider range of aftermarket vehicle-backup systems since our last report, including new and improved designs.

All such systems are intended to help drivers detect objects within the blind spot behind the vehicle.

New are camera systems such as the Audiovox and ParkFX we tested that offer a “picture in the mirror” feature. The display is on a mirror that fits on top of or replaces the existing rear-view mirror, so you don’t have to choose between looking at the display and at the rear-view mirror while backing up. ParkFX also combines a camera with an audible sensor, so you can see and hear potential trouble. We would like to see more backup warning systems on the market that combine camera and sensor technologies.

Backup systems are typically marketed as parking aids, not safety equipment. But our tests show that the camera models can also help drivers avoid backover-accident injuries and fatalities.

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.

Track Your Buddies on the Highway With New Gadget

TomTom's portable car navigator systems have a new feature called TomTom Buddies. Stuff magazine reports that the new friend tracking system allows people to not only send messages back and forth but keep track of where their friends are located.

Called TomTom Buddies, the feature lets you track your mates wherever you go – and in return, they get to track you too.

All you do is invite other TomTom users -- you'll have to shun your Garmin and Navman chums - to be your authorized 'buddy'. The idea is that the Buddies service will be like an exclusive club through which you can send each other text messages and locations you think are interesting.

If you feel like being a loner for a bit you can select the privacy option which lets you hide your location. Plus, if any of your Buddies keep sending you many Points of Interest -- dodgy McDonald drive-ins, for example -- you can delete them.

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).
