They primarily exist to set off my radar detector.
But seriously they are kind of handy. The one's on my 17 Ram (front and rear) are pretty accurate and at times I wish I had them on the front of the challenger.
Especially if they could detect high curbs.
My previous radar detector lost its status as 'current radar detector' once the collision avoidance stuff got to be on the majority of vehicles. I could turn off K band to avoid the constant false alarms, but there are 2 adjacent towns whose police use K band instead of Ka like the rest of the civilized world, so I had to find a better fuzz buster eventually.
I did find a new one last year that requires no special treatment to deal with the non-police K band signals (it ignores them), and best of all it was affordable (<$100). And ironically enough, it was the upgraded/newest model of the previous detector, so there was no relearning its functions or getting used to its differences. It is virtually the same as the old one, but better in all the ways the old one performed poorly.
PM me if you're interested in putting the grab on one like this, and I will go write down the model number and such to send across so you can shop around to see if they are worth giving a day in court in your particular setup...pun UN-intended!
