My brother recently got one of these on his car, but he found he really didn&#x27;t save anything by having it. Based simply on the amount of time driving during &quot;peak hours&quot;, namely rush hour&#x2F;when everyone is leaving work, he lost any discount he was pitched by the insurance company. This isn&#x27;t really anything he has any control over.<p>In that case he seems to be getting a snow job from an insurance company that is using the the idea of quantified self&#x2F;living to seize a larger part of its customers&#x27; lives, likely without really paying them back anything for the intrusion.
