If the lidar is close enough to both vehicles the lidar should be able to single out an individual vehicle. However if both vehicles are relatively close to each other and far from the lidar, the lidar could (probably) measure a larger faster vehicle.
A typicle lidar beam is just under about 2 feet wide at a range of about 500 feet. At 1000 feet the beam is just under 4 feet wide. Another consideration is beam to scope (aim device) accuracy. The beam and scope must be closely aligned, otherwise the operator does not really know exactly where the lidar is pointing.
