I did the DFW to Austin drive earlier tonight and on the way down a 2009 F150 set off K-Band from about 1/2 a mile away. It then grew to about full strength when he was 1/4 of a mile away and stayed strong until he passed me and thats when it still went strong with side arrows and then the front arrow pointing him out. It wasn't a Trooper or LEO of any sort. It was some kid driving along in his truck. From what I could tell he didn't have any sort of RD and he wasn't using a gun to mess with me since I watched him the whole time he was in front of me.
I'm wondering if anyone here has a potential explanation as to why he set off my V1.
It was set to stock 'A' while this was going on.
