That's not true. LIDAR does disperse. At something like 1,000 yards, the beam is something like 15 to 25 feet wide, and it bounces off of things like guard rails, etc, so detectors can pick up reflections, and the huge diffuse beam from far away, outside the range where the officer can determine your speed.
When I lived in Bethesda, I had a detector that detected all the microwave bands and also lidar.
There was a state trooper who always sat at the DOT yard on the side of River Road running LIDAR. I know he ran LIDAR because I got a ticket before getting the detector, and it said (lidar) next to the speed on the ticket. The detector works, but not perfectly, and not always in time to avoid being in his range, but it is still better to have a little insurance than to have no insurance. I only once drove past his speed trap without getting a signal until I was well within range, but that was at 1:30 in the morning and I was the only car on the road.
You should never rely on a radar detector to allow you to speed and as your only defense against getting pulled over. It is a tool that should be one of many in your tool kit.
First, you need to learn how to use it. Don't just open up the box, stick it on your windshield and race around town thinking you're immune from tickets now. Drive around at the speed limit for a month or two and learn to understand what it can and cannot tell you, and learn patterns of where cops are most likely to be, and if you find a place that falses all the time but looks like a good place to hide, don't just ignore that false, cops will hide in areas that have false signals hoping to catch people who have learned to ignore that alert. Also, you need to learn how much distance/time between getting a signal and when you see the police car. Adjust your speed accordingly, so all you have to do is take your foot off the gas or downshift in order to enter his range at the legal speed.
Second, you always have to be aware of the road conditions -- if traffic is really light, you're at a higher risk of instant on radar. If traffic is really heavy, you can be more certain that you won't stumble upon a speed trap without getting a warning well in advance.
There's all kinds of articles on the internet that go into detail discussing the fine art of using a radar detector properly.
