Why buy a new car when you can improve the one you have with the latest technology? Here are two new methods that will not only make life behind wheel more fortable but may also end up saving you money.
WI-FI on Wheels
It’s not enough that children plain about having nothing to watch on television. These days, they even plain about having nothing to watch in the car. Fortunately, for every unsatisfied youth, there is a new technological solution: Wi-Fi Internet access for the back seat of your vehicle.
In the United States, Chrysler is the first to offer such a system, which turns any Chrysler or Dodge into a Wi-Fi hotspot. Called UConnect, the $499 dealer-installed option is a high-speed cell-like Internet connection with a wireless router that sits in your car’s trunk. Monthly service costs $29 for Internet access, which is available to any device that has Wi-Fi and is within 100 feet of your car.
With UConnect, passengers can check emails messages on a laptop, send instant messages to friends or watch YouTube videos online. It allows passengers to search for movie listings on a smart phone or connect a Sony PSP video game player to the Web. It also offers the ability to freely upload photos from a Wi-Fi-equipped digital camera to an online sharing service like Flickr.
For critics who claim that putting Wi-Fi Internet access in a car feeds the danger of driver distraction, parents may well disagree: What’s more distracting, the temptation to check email or a lot of children talking to you from the back seat?
Watch Your Back
Blind spots behind cars and SUV’s make backing up dangerous as well as potentially deadly for children. Nationally, the group Kids and Cars estimates that two children a week are killed by cars backing up. The Transportation Department is establishing visibility standards for future vehicles, but there’s no need to wait.
A back-view back system can be an expensive option in a new car. In the 2008 Subaru Tribeca, for example, the back-view camera option is available only in connection with the inner navigation system, at a price of $2,400. And professionally equipped systems can cost $400 or more. However, there are now inexpensive back-view packages you can help yourself, such as the $130 Audiovox ACA250 Wireless Vehicle Rear Observation System. It includes a camera that increases on a back license-plate holder and grasps onto a vehicle’s backup light. It can send a back-view image to a small L.C.D. Monitor that can be carried into electronic equipment and increased on the dashboard(仪表板).
Audiovox claims the camera housing is not afraid of dust. In some areas where radio waves are plentiful, the image can be affected by occasional interference, but the picture, with its wide 110-degree camera point, is good enough to see things or children behind you.
