> ...what crosses the line about monitoring driving behavior? First and foremost, it's only ever going to be used against me if it is used. I would basically have to bet I was never in an accident, which, given I've been hit three times while legally stopped in the last 5 years, I'm not willing to do. I suspect for the vast majority of drivers, the monitor is a net cost, not a net savings. But also, there is not a one-to-one relationship between liability and safety. Insurance companies care about liability first, and if they care about safety, they care about it second. I'd like to see some studies on how these monitors influence driver behavior before even considering getting one installed. For another, the monitors lack context. It is safer to travel at 75mph in a 65mph zone if traffic is going 75mph and the road (and your vehicle) otherwise supports that speed. (Put lazily without citation: At that speed there is almost no difference to increased speed in terms of serious injury or fatality, but at that speed variance, the likelihood of a crash occuring is higher. Net result: more serious injuries and fatalities driving at the slower speed.) But the monitor will only see you going 10mph over the speed limit. And then, as a sibling poster mentions, there are the privacy issues. If it monitors your location, it is monitoring far, far more than your driving habits.
