ask the cop
It indicates a slow moving vehicle, which would be operating below normal traffic speed.
Your ability to maintain control of your vehicle is determined by your speed. Driving within the posted speed limit and adjusting your speed based on road conditions, traffic, and weather can help you stay in control of your vehicle.
No. They were not travelling at a safe speed and did not have control of their vehicle.
Radar or LIDAR (laser measurement of speed) has to be directed toward or away from the path of a moving vehicle, as it measures the speed vector between the measuring device and the vehicle. Traffic radar or LIDAR will not measure the speed of a vehicle moving at a right angle to the direction it is pointed.

speed
The speed in which the traffic is moving, matching it's speed at a safe distance
The answer is "yes." Traffic radar monitors both the speed of the vehicle in which is it mounted and the speed of "target" vehicles coming toward or moving away from it. On the radar display, the officer sees two speeds: "patrol" (the speed of his vehicle) and "target" (the speed of the vehicle the radar is tracking). the target speed measurement is equally accurate, whether the patrol vehicle is moving or not.
speed
Yes, accelerating from a standstill typically uses more fuel than maintaining vehicle momentum in slow-moving traffic because the engine has to work harder to overcome inertia. In slow-moving traffic, keeping a steady speed and avoiding unnecessary acceleration and braking can help conserve fuel.
The amount of wildlife or 'traffic' in that area
It is important to obey the speed limit for safety and avoid getting a ticket. If traffic is moving faster than the speed limit, it is best to stay at or below the speed limit and let others pass if necessary. Your safety and following traffic laws should be a priority.
