Well I put my LI system on about 2 years ago on my 2008 Corvette I believe. I really only had one save in those two years until this week. Even that one save made it worthwhile in my book. Starting last week there was a state cop sitting under a bridge on my commute to work. The PSL is 45, I was doing about 70 one day last week and he hit me, next I slowed down and turned off. He pulled out, I thought I was screwed! But he went after someone else! Since that day he has hit me two more times. I'm confident that at least one of the three times he hit me I would have been pulled over if it weren't for the LI system.
