I was driving 45mph in city limits with a 35mph PSL in an area I know is death for speeding over 5mph. The town is small and the main road is max 35mph so they target all cars 5 over the limit. I get an alert from the LI and shut it off just when it said "pro-laser" and spotted the cop no more than 50ft from me on the right hand side. The ambush was less than 300ft when I first got the alert. If your setup isn't JTG, there is a high % that you just got a ticket.
On another note, driving back home through that city using another back road, I didn't have the urge to speed so I went at PSL and BAMMM!!!. I/O at 300ft on a curve at night.
I thought these 2 encounter on the same night was amazing how the city cops targets speeders at such close distance. Almost all my lidar encounter in this city is < 500ft.
