Nope, the radar in mobile patrol cars is just your standard radar. Lidar is only used in the hand held devices, since it has to be pointed at the car in particular (basically because it's too accurate, the beam is too narrow)
HWP cars do have radar that can be used while mobile, but since it's radar, it's only really useful if you're the only car that could possibly be detected by it (read up about how radar works). It works the same way a stationary radar would work, but adjusts the calculation based on the HWP car's speed. The officer has to select whether the radar should adjust for oncoming cars or cars heading in the same direction (because of the radar doppler effect).
Also why most of the time you see HWP cars parked on the side of the road with the officer holding a lidar gun instead.
