Technology can hurt a driver as much as it can help him.
For example, those convenient automated toll systems (i.e. EZ Pass, FasTrak, SunPass, etc.) can also use their time/distance data to figure out if you were speeding.
GM may be hitting even closer to home with a new OnStar feature.
Right now General Motors will use OnStar to pass on information to their GMAC Insurance arm about your annual driving mileage for possible insurance discounts.
