The trooper's car also has to be closer and perpendicular to the traffic in order to get the line of site shot out a side window.
LIDAR also requires high concentration from the officer vs Ka band instant on. It is much more stressful for troopers and the net return vs radar is minimal, as radar is very difficult to beat in court.

I try to see "what an officer sees" as I travel. If I were using LIDAR, I would nearly always be using it on a grade. On flat terrain, it is more difficult to target the oncoming vehicles. And most of the training emphasizes front targeting. 95% of all LIDAR tickets are from the front, rather than from the rear. So if you are travelling on a long downward slope, especially around a long sweeping curve you are especially vulnerable, because visibility at the bottom of a hill looking upslope makes target acquisition much easier. So it is a good idea to program that terrain profile permanently into your brain, and when you are sailing along on such terrain, be especially focused. The good thing about LIDAR is also the bad thing about LIDAR. It requires effort and targeting, which requires time, which makes it non-conducive to blind side attacks behind trees, bridges, etc. Unlike radar, which is excellent for ambushing.
Of course they are using both, not to mention VASCAR and pacing, so it is up to the motorist who wants to travel both safely and quickly to be cognizant and conversant with all methodologies. And really, this means everybody, since 100% of all motorists exceed the speed limit, and usually it happens at least once EVERY time they drive. Even the condescending "holier than thou" safety Nazis. They speed every day also, often unintentionally, and often due to artificially low speed limits designed to generate revenue rather than achieve safety.
You see, in many cases speed limits are set artificially low as a
revenue generator, which means that speed limits are often used for
taxation rather than
safety. So in this case, it is up to the citizen to avoid the entrapment and use rational countermeasures to evade this form of "taxation without representation".
Highway engineers report that a speed limit should be based on the principle of the "85th percentile". Meaning: the speed at or below which 85% of the public would travel on a particular roadway if there were no speed limit at all. When they set it at the 70th percentile, as they do setting it at 55MPH on certain segments of 80 and 287 and the GSP, they are intentionally ignoring safety and introducing taxation. That is unjust and that is why there is a radar detector and jammer industry.
If they set the speed limits properly at the 85th percentile, speeding would be rare and actually unsafe, and enforcement would be justifiable. So for Interstate 80 where there are 3-5 travel lanes, the 85th percentile speed would be somewhere around 77MPH. Not 65.
But that is not where we are right now. So be aware, be educated, and travel quickly and safely with the available knowledge and tools that prevent the unjust taxation without representation from affecting you and your insurance bill, not to mention your very right to motion.
And let me just postscript this with the observation that I am talking primarily about Interstates and Freeways and GSPs and NJTs, not local roads. On local roads, neighborhood roads, etc. you should obey the speed limit, and often go even slower. On congested local roads, main streets, Route 17 Paramus, Route 46 Lodi, 4 lane undivided highways, etc, where decisions are being made quickly in real time by distracted and underqualified drivers, it is best to exercise excess caution in order to arrive alive.
