It's Easier for Car Insurance Companies to Track Us Than They Let On

As far as the future of car insurance goes, all signs point to telematics: i.e., rates determined by a device that tracks metrics such as how fast you drive, how hard you brake, and when you're out and about. If your driving habits are deemed safe, you'll get discounted coverage.

Sounds great, unless you're concerned about privacy. Although many telematics programs state they don't collect locations of vehicles—indeed, most "trackers" aren't even equipped with GPS—Rutgers researchers have found that a driver could reveal her route to a car insurance company with no more information than her home address and the speed she's traveling.
