Hey guys, I was leaving Notre Dame Campus today and there was an 80s model Mercedes sedan behind me. As it got within 300 feet I got four light strength of Ka. It pulled up behind me at a stop sign and I got full tone. Thinking SURELY that there was a cop way back at the other end of the entryway, I decided to test it out. I let the mercedes pass me on the road we pulled out to. The arrows turned, and the Ka was VERY faint in front of me. I then (feeling like a d-bag at this point) passed the mercedes. Arrows turned and I got full tone from the rear. This guy was NOT a cop and this was NOT a LE vehicle. The guy was in a polo smoking a cigar and there was no sign of radar, two way radios, antennas, etc. WTF?
