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.

LaneFX proven better solution to the blind spot problem than stick-on convex blind spot mirrors

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.

Steering Wheels Get More and More Buttons

The steering wheel is quickly become the control center for the entire vehicle. Auto manufacturer's are using the steering wheel to add new buttons and controls for everything from controlling the radio to switching gears. USA Today reports that many cars already have 10 to 15 different buttons on the steering wheel:

The fingertip frenzy isn't just about luxury cars, either. Sure, the $73,750 Range Rover SUV offers 10 buttons or toggles, not including the horn. And the $49,100 Acura RL sedan has 16, in addition to two thumb paddles for manually changing gears. But Toyota's humble — albeit fully-loaded — $26,040 Prius gas-electric hybrid sedan includes 15 places to mash a thumb into the steering wheel.

Automakers say the buttons help motorists keep their fingers on the wheel instead of having to fiddle with dials and knobs on the dashboard, making driving safer.
