^ True to an extent - but far from true, when taken as a blanket-statement.

The problem is that although we've all been led to believe that police LIDAR is an "instantaneous" speed-measuring device, it's actually far, far from that.

While the vast majority of speed locks do occur at the "at or less than 1/3 of a second" speed touted by the various manufacturers, the actual lock-time can be many times longer - and not infrequently, vehicles, at-random, without being equipped with any type of countermeasures, can return with no-lock or spurious errors.

Look at any of the various hobbyist testing videos - when they're just clocking passing traffic, you'll see that this is true. Now, keeping in mind that only a small fraction of any such test is what's actually "on tape," and combine this with the typical difficulty in terms of obtaining an "enforcement scenario" reading (vehicles traveling at-speed, without the help of a stabilizing tripod setup, etc.) - it's not at all unlikely for a good detector to catch scatter, nor is it impossible for such "saves" to occur.

The key, I believe, is that instead of debating whether such "saves" can occur (far from impossible, such "saves" take place nearly every-day - look on RD.net, there's many, many tales of such saves, and not all from the V1; similarly, look at the stories of those who have jammers - and note how many times their high-mounted detectors have provided advanced-notice/"save" [one of my own tales is among these ranks]), is rather to point out the fact that yes, one can get lucky and have such a "save," but your overall odds against are such that the only viable recommendation to give, when speaking of proper LIDAR defenses, is to advise for the use of a good jammer setup.
