This is a nice follow-on. The one additional thing I'd point out is that when a Class B driver gets the quote from this carrier of $1,684 but gets a quote of $1,100 from another carrier, they're likely to head for the cheaper option, providing further benefit to the carrier using the trackers.

Also, I haven't worked in property/casualty insurance, but my understanding of these trackers is that they don't include GPS capabilities, almost certainly for those sorts of reasons you mention. The risk of bad headlines incentivizes carriers to do what they can to ensure that the false-positive Class B drivers are not correlated with anything potentially sensitive.
