Lidars are highly directional and have low duty cycles so even when large numbers are present the amount of interference is small. So you do have to model a certain amount of noise in your lidar returns but you have to do that anyways due to things like sun reflecting off of shiny surfaces. Noisy sensors have been a fact in autonomous robots for as long as there have been autonomous robots and there are a variety of standard techniques for coping.
