I was riding with my buddy and he was driving about 75 in 65 maybe a little higher. I should note there was no one else on the road. He got lit up with 34.7 and braked hard immediately, he was down to 65 in less the a second. The LEO turned the radar on really early for using IO, it was atleast a 3/8 mile and he was on the other side of the road in the grass with all his lights off. He didn't turn out to pull us over for a minute. When he pulled us over he got his info and went and wrote up the ticket, and when he came back he said he wrote the ticket for driving 80 in a 65. My friend told the LEO he was not driving that fast and asked to see the speed he locked him in on. The LEO replied I didn't get your speed locked and I don't need to. He didn't argue and just took the ticket but we both think he should take it to court. One of my friends was goin to college for Law Enforcement and on the ride alongs he went on they all told him you need a lock on the speed otherwise you have no proof.
The car he was driving was 2011 Dodge Charger RT. The speedometer is completely accurate. The detector is a 78se and keep in mind that only filters a signal for about 150ms. I believe the LEO didn't get a speed locked until he was under PSL and saw his headlights dip from slamming the brakes and got mad and wrote the ticket because he thinks he is the law and can do whatever he wants.
