Sales are booming for lo-jack style devices designed to remotely kill cars when their owners fall behind on payments. These cars are sold to people whose credit has been downchecked to "B," on lots where cars cost more, loan terms are worse, and they contain GPS units that make the car's location continuously available to the dealer, credit-company (and others) so that they can more easily repossess the cars.
Companies such as OnStar are beginning to make use of their remote controls for purposes other than theft prevention: for example, the company promises to throttle the engine of any car that they're told is involved in a police chase.
Presumably these remote-kill devices are no better or worse secured than, say, the tax-records of every British parent (repeatedly lost by the tax authority), or the computer systems of giant credit-reporting bureaus, or the networks of the 100+ embassies and foreign service offices penetrated by the GhostNet espionage ring.
Designing devices that are intended to be remotely disabled, against the owner's wishes, is like designing one of those science-fiction-movie spaceships with the inconveniently placed "self-destruct" button. I always wondered about those: wouldn't starship engineers turn out a better product if they designed it from the ground up never to explode?
And wouldn't these cars be more secure if they were designed never to be remotely controlled against the owner's wishes?
The devices, which are required by a growing number of subprime loan contracts, are the product of a revolution in telematics -- the blending of telecommunications and wireless technology.
The devices are usually controlled remotely by the dealer or lender and are linked to the vehicle's powertrain. They usually cut out the power several days after the payment is due. Before the deadline, the driver is treated to a concert of tones and flashing indicators signaling that the deadline is approaching. There are also warnings after the deadline has passed.
Their proponents call the devices a win-win for consumers and finance companies. They make it possible for dealers to sell cars to people who would have a hard time getting a loan otherwise. The buyers end up paying a somewhat lower interest rate because the risk to the lender is less.
The products also include global positioning, or GPS, to speed up the repossession of the vehicle, if necessary.
Most tech-media takes on the iPhone’s 10th anniversary are bland and self-congratulatory, but I like Tom Warren’s at The Verge. He laments how Apple’s pocket computer killed his inner nerd. As a youngster, he’d be constantly tearing down and building computers, even in the sweltering heat of summer. But now… …All of that tinkering and […]
Snazzy Labs built a startlingly powerful Mac with only $70—editing the video above on it to prove it!
I suffer from mild RSI: a warning to stop, but one that goes away when I do stop. The trigger is using a mouse for extended periods. The alternatives for general everyday computer use aren’t great for my work habits, which center on precise pointing and clicking, so I’m in the bad habit of mousing […]
Aside from specific apps needed for work, the most casual Mac users can probably survive without anything more than the bundled software. iLife is a surprisingly capable office suite (Apple even promotes Keynote as a tool for interface design), and recent versions of Safari are more energy efficient than any other macOS-compatible browser. But if […]
Despite the upfront cost, electric toothbrushes are much better at removing plaque than those freebies from the dentist’s office. For those who struggle to fill the American Dental Association’s recommended two minutes of brushing time, or anyone with limited dexterity, a sonic toothbrush can give your oral care routine a boost.To keep your chops healthy […]
Learning a new language will give your resume an upgrade, sure, but it will also provide a huge cognitive boost for mental tasks outside of translation and conversation. Bilingual brains have been shown to be better at handling multiple concurrent tasks, and gaining fluency in a new tongue is an amazing way to improve memory, […]
