Last night I was cruising up I-65 just south of Birmingham. Traffic was fairly light. I had a gentleman in a Volvo that was keeping up with me for quite awhile
We had been within eye sight of each other for a good 20 minutes and a lot of the time we were within 20 meters. For the first 20 minutes or so I had no alerts and traffic was very light. Then out of nowhere I get a full strenght hit of KA from the rear. At this point the only person around is the gentleman in the Volvo and he is roughly 30 meters behind me. I continue to get the full strength for a steady two minutes then decide to slow down to let the volvo pass to see if I can get a better idea of where it was coming from.
Sure enough as the volvo came up on my side the detector followed its motion and then reported the signal from the front, however now it was only at a 4 strength.
The Volvo did have a radar detector on the windshield...i am not exactly sure what it was but it looked like the "Silver Bullet" that is advertised in AutoSport Magazine.
I am very new to the RD community so interested in seeing what kind of explanation you guys can enlighten me with.
