Then again I "drive to drive," I imagine someone who was a bit more distracted or less focused could really use the alerting of a detector.
This + jammer.
The detector doesn't work if they are just cruising around anyway, so you always have to keep an eye out. Really the only time it works for me is when I'm on the freeway. I try not to drive fast in the city because they can just use their eyes and see that I'm speeding.
