Going NB on the PA NE Extension towards Allentown. I was doing about +25-28 on a Sunday morning a few weeks back (clear left lane, no tailgating, or weaving). I did that for a good 5-10 miles, and I started to see a Nissan Rogue guy tailing me as a rabbit. Fair enough, I did have the R3 running 100% K band sensitivity with K Filter On (TSF Off). I start to reach a upward slope which banks to the right, then downwards slope banking to the right as well. Waze lets me know theres a cop ahead. Shortly after, the R3 alerts to K-band. Not taking a chance, I cut to the right behind a slower moving vehicle and slow down to about 75ish. I think the PSL is 70. Nissan Rogue guy guns past me doing my original speed. No sooner do I crest the hill that within 500-700 feet is a PA state trooper on the right ready to pounce. And pounce he did, he nearly ran me off the road in fact. He pulled in, gunned for Nissan Rogue guy, and I bet that wasn't a pleasant conversation. +1 for the R3 + Waze. Otherwise my goose was cooked that morning. K band is lethal in PA, between all the falses with drones & BSM, it's hard to pick out legit threats.
