Range, Heading, and Entity Type Limitation

The lidar gun can clock AI vehicles up to your view distance (1100-1800 ft max.). Civilian vehicles clock range is limited by FiveM’s OneSync to 400-500 ft. It also has no built-in entity type limitations, it can clock vehicles, bicycles, peds, animals, and aircraft.

Cosine Error

An effect when lidar gun (and therefore beam) and target are not perpendicular to each other. The larger the angle between the instrument and the target the larger the error in clocking a vehicle speed. This error results in an underestimation of the vehicles speed, meaning the display will show a speed less than that of the actual target speed. While we can't actually measure the tangent or simulate the lidar beam, it is a rough estimation based on heading. The reduction also has a random scalar, to help simulate the different surfaces the beam may be hitting each with a different tangent.

It is important for players to be trained on this and understand the effects of Cosine error. The image below describes the mathematical relationship. You can read more at the link below.
